## What is a prime number?

A Prime number is a positive integer that can exactly divided by one and itself.

**For example**: 13 is a prime number. 13 no numbers multiply into 13 to make 13 except for 1 and 13

Another way of understanding of prime number is that a prime number is a positive integer that is not the product of two smaller positive integers.

**Example:** As we see 4 can be made by 2 × 2 so this is NOT a prime number. It is called composite number.
