### How do you find a composite number?

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.
