What is a multiple, a prime number, and a composite number?

I'm not sure how to word the other two words but a prime number is a number that is only divisible by 1 and itself. Eg 13 is a prime as it is only divisible by 1 and itself.

A multiple is any product of two numbers. For example, 4 is a multiple of 2, 1, and 4. 4*1 is 4, and 2*2 is 4. A prime number is a number that only has itself and one as a factor. For example, only has 1 and 17 as whole number factors. A composite number is just the opposite; for example, 4 has 2 and 2 as a factor--therefore, it has more than just 1 and itself.
