There are different types of numbers in Mathematics such as whole numbers, natural numbers, integers, rational numbers, prime and composite numbers, etc. And all these numbers play an important role in maths.

In this article, we are going to discuss the composite number, examples of composite numbers, a list of composite numbers, and much more.

Let us start with the composite number definition and examples.

### What is a Composite number in Math?

A number that has more than two factors is know as composite number.ORA number that is divisible by more than two numbers is known as a composite number.

Remember all even numbers are composite numbers except 2 because 2 has only two factors 1 and 2. The smallest composite number is 4. And all composite numbers are natural numbers.

### What are some examples of composite numbers?

24, 40, 77, 100, 990, etc. are some examples of composite numbers:-

**24 =**Factors of 24 are

**1,2,3,4,6,8,12,24.**( 24 have more than two factors).

**40 =**Factors of 40 are

**1,2,4,5,8,10,20,40.**(40 also have more than two factors).

**77 =**Factors of 77 are

**1,7,11,77.**(77 have more than two factors).

### List of composite numbers from 1 to 100

There are 74 composite numbers from 1 to 100. They 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.

### Composite numbers from 1 to 50

There are 34 composite numbers from 1 to 50. They 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.

### Difference between composite numbers and Prime numbers.

**Composite numbers**have more than two factors while

**Prime numbers**have only two factors.

All

**even numbers**excluding 2 are composite numbers while**2**is a**prime number**.**Examples of composite numbers**are 30, 40, 18, 106, etc. While

**examples of prime numbers**are 2, 3, 5, 7, 17, etc.

### How to find factors of composite numbers?

We may find the factors of any composite number by dividing it from other numbers & check its remainder to be zero.

If the remainder will be zero and the quotient is not in decimal form then that number will be the factor of that composite number.

**1. Example:-**

56 = Numbers by which 56 is divisible are 1, 2, 4, 7, 8, 14, 28, and 56.

So 1, 2, 4, 7, 8, 14, 28, and 56 all are factors of 56.

**2. Example:-**

72 = Numbers by which 72 is divisible are 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 36, 72.

So 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 36, and 72 all are the factors of 72.
