What is the difference between composite and prime?

Composite numbers are those numbers that retain more than two factors. It implies that the number except one and itself can be divided by other numbers also. A prime number is a positive integer which has only two factors i.e. one and itself. It implies that the number can be divided only by one and itself.

What does prime and composite numbers mean?

Definition: A prime number is a whole number with exactly two integral divisors, 1 and itself. Definition: A composite number is a whole number with more than two integral divisors. So all whole numbers (except 0 and 1 ) are either prime or composite.
