Composite numbers space numbers with more than two factors. Numbers can be share on the communication of the variety of factors they have. If a number has actually just two components - 1 and also the number itself, then it is a prime number. However, most numbers have an ext than two factors, and they are called composite numbers. ~ above this page, us will find out the difference between prime and also composite numbers, the the smallest composite number, and odd composite numbers. The critical one is interesting because there are numerous odd composite numbers, uneven 2, which is the only also prime number.

What are Composite Numbers?

Composite numbers can be characterized as organic numbers the have an ext than two factors. In other words, a number the is divisible by a number other than 1 and also the number itself, is dubbed a composite number. Let’s learn more about composite numbers with examples.

Examples of Composite Numbers

4, 6, 8, 9, and 10 room the first few composite numbers. Let's take 4 and also 6. In the over example, 4 and also 6 are called composite numbers due to the fact that they are made by combining various other numbers. This idea is important and also we used it in a theorem referred to as the basic Theorem the Arithmetic. Let's continue to understand the necessary features the composite numbers.

Properties that Composite Numbers

A composite number is a hopeful integer that deserve to be formed by multiplying two smaller hopeful integers. Note the nature of a composite number detailed below:

All composite numbers room evenly divisible by smaller numbers that can be element or composite.Every composite number is comprised of two or much more prime numbers.

Let us have a look at the nature of the composite number 72 in stimulate to know the concept in a better way.


This figure shows the by multiplying these optimistic integers we get a composite number.

How to discover Composite Numbers?

In bespeak to uncover a composite number, we discover the factors of the offered number. If the number has more than two factors, then it is composite. The best means to number out a composite number is to carry out the divisibility test. The divisibility check helps united state to recognize whether a number is a prime or a composite number. Divisibility means that a number is split evenly (with no remainder) by one more number.

To perform this, inspect to view if the number have the right to be separated by these typical factors: 2, 3, 5, 7, 11, and also 13. If the given number is even, then begin checking through the number 2. If the number ends through a 0 or 5, then check it by 5. If the number can’t be divided by any kind of of these provided numbers, then the number is a element number. Because that example, 68 is divisible by 2, which method it has factors other than 1 and also 68, so, we have the right to say 68 is a composite number.

Types of Composite Numbers

The two main species of composite number in maths are odd composite numbers and also even composite numbers. Allow us have actually a look at the 2 of them individually:

Odd Composite Numbers

All the odd number which are not prime room odd composite numbers. For example, 9, 15, 21, 25, 27 room odd composite numbers. Consider the number 1, 2, 3, 4, 9, 10, 11, 12 and 15. Here 9 and 15 are the odd composites due to the fact that these 2 numbers have odd divisors and satisfy the composite condition.

Even Composite Numbers

All the also numbers which room not element are also composite numbers. For example, 4, 6, 8, 10, 12, 14, 16, are even composite numbers. Consider the numbers 1, 2, 3, 4, 9, 10, 11, 12 and also 15 again. Right here 4, 10, and 12 space the also composites due to the fact that they have also divisors and also satisfy the composite condition.

Smallest Composite Number

A composite number is defined as a number that has divisors various other than 1 and also the number itself. Begin counting: 1, 2, 3, 4, 5, 6, .... For this reason on. 1 is not a composite number since its sole divisor is 1. 2 is no a composite number because it has only two divisors, i.e., 1 and the number 2 itself. 3 is no a composite number since it has only two divisors, i.e., 1 and also the number 3 itself. Let’s look at number 4. The divisors room 1, 2, and also 4. Number 4 satisfies the criteria of a composite number. So, 4 is the the smallest composite number.

Composite numbers Examples

Example 1: recognize whether 486 is a composite number or not?


The provided number is 486. Its factors or divisors are - 1, 2, 3, 6, 9, 18, 27, 54, 81, 162, 243, and also 486. This reflects that the has determinants other 보다 1 and itself.

∴ 486 is a composite number.

Example 2: settle the following riddle: "I lie between 30 and also 40; I have actually only 2 prime factors. The sum of mine prime factors is 5; who am I?" A composite number or a prime number.


The sum of the prime components of this unknown number is 5. We recognize that the element numbers whose sum is 5 are 2 and 3. Now, we require to uncover a number that has 2 and 3 as its just prime factors and which lies in between 30 and also 40. Let us see the prime factorization of 36: 36 = 2 × 2 × 3 × 3. So, 36 satisfies the provided conditions.

∴ 36 is the compelled number. The is a composite number.

Example 3: What is the product of the an initial five composite numbers?


To uncover the product the the an initial five composite number let us first list out the composite numbers.

The an initial five composite numbers space 4, 6, 8, 9, 10

The product the the noted composite number = 4 × 6 × 8 × 9 × 10 = 17280

The product the the first five composite numbers is 17280.

FAQs ~ above Composite Numbers

What room Composite number in Math?

In math, numbers are the an easy building blocks. Composite numbers are the types of numbers that have much more than 2 factors. For example, number 6 is a composite number it has actually 1, 2, 3, and 6 together its factors.

How to find Composite Numbers?

To discover whether a provided number is composite, us just discover the number of factors that has. If it has an ext than 2 factors, climate the number is composite. Because that example, 4 has three factors, 1, 2, and also 4. So, that is a composite number.

Is 2 a Composite Number?

No, 2 is not a composite number, the is the only even prime number. A composite number has an ext than two factors, other than 1 and also the number itself. Here, 2 has actually only 2 factors, 1 and 2 itself. Therefore, 2 is a prime number.

What space the Composite Numbers between 1 and 100?

The composite numbers in between 1 and also 100 are-

4, 6, 8, 9, 10, 12, 14, 15, 16, 18, 20, 21, 22, 24, 25, 26, 27, 28, 30, 32, 33, 34, 35, 36, 38, 39, 40, 42, 44, 45, 46, 48, 49, 50, 51, 52, 54, 55, 56, 57, 58, 60, 62, 63, 64, 65, 66, 68, 69, 70, 72, 74, 75, 76, 77, 78, 80, 81, 82, 84, 85, 86, 87, 88, 90, 91, 92, 93, 94, 95, 96, 98, 99, 100.

What is a Composite Number and Prime Number?

A number the is divisible by a number various other than 1 and also the number itself, is referred to as a composite number. For example, 4, 6 are composite numbers. Whereas, a number that is divisible only by 1 and itself is referred to as a prime number, like, 2, 3, and 5.

What is an Odd Composite Number?

All the odd number (excluding 1) which are not prime space odd composite numbers. Because that example, 9 and 15 are the strange composite numbers.

What is the smallest Composite Number?

A composite number has much more than two factors, other than 1 and also the number itself. Here, 4 satisfies this condition, and there is no various other number smaller than 4 i beg your pardon is composite. Therefore, 4 is the the smallest composite number.

What is the Difference in between a Prime and a Composite Number?

A prime number has actually only 2 factors, 1 and the number itself, whereas, a composite number has an ext than two factors. Because that example, 5 has actually only 2 factors, 1 and 5, so that is a prime number. Whereas 6 has 4 factors, 1, 2, 3, and also 6, so that is a composite number.
