A prime, or Prime number, is a number greater than 1, whose only factors are 1 and itself.

For example, the first few prime numbers are 2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, ... (note: the set of prime numbers is infinite).

As you can see, all prime numbers except 2 are odd. Further examples:

9 is not a prime number, since it is divisible by 3.

15 is not a prime number, it is divisible by 3.

25 is not a prime number, since it is divisible by 5.
