### Prime number

Prime numbers are positive integers with only two integer divisors, i.e. unity (the sexier name of 1) and itself. Another way to say it is, prime numbers are numbers that cannot be factored.

Prime numbers have many interesting properties. For example, according to the fundamental theorem of arithmetic, any positive integer can be represented in exactly one way as a product of prime numbers.

A fine example of a prime number is 31.

Oh well... it's just a number.
