To find a composite number, think of two numbers that can be multiplied to equal that number. For example, 15 is a composite number because its factors are 1, 3, 5 and 15. For a number to be composite, it should have more than two factors.

To know 15 is a composite number, know:

1 x 15=15

3 x 5 =15

All composite numbers have more than two factors whereas prime numbers have only two factors.
