Prime numbers are integers greater than 1 that are exactly divisible by themselves and the number 1. Examples are 2, 11, 23, . . .
Composite numbers are those which do not have this property, that is, all the other integers. You can make up each composite as a product of prime numbers. Examples are 6 (2*3), 39 (3*13), 91 (7*13). . .
