What does prime and composite mean?

What are Prime and Composite Numbers? A prime number is a number which has exactly two factors i.e. ‘1’ and number itself. A composite number has more than two factors, which means apart from getting divided by number 1 and itself, it can also be divided by at least one integer or number.
