A '''prime number''' is a number that is evenly divisible by no other number except for itself and 1. A number which is not prime is called a [[composite number]]. The classifications ''prime'' and ''composite'' apply to positive integers greater than 1, though there are related concepts in other branches of mathematics. Note that 1 is neither prime nor composite.
The smallest prime numbers are 2, 3, 5, 7, 11, 13... . An exmple of a composite number is 6, which is easily divisible by both 2 and 3.
