Prime numbers have two factors, 1 and the number itself.
All other whole numbers are known as composite.
The only even prime number is 2 because all other even numbers will have the number 2 as a factor.
The number 1 is not a prime number because it has only one factor - 1!
The list of prime numbers starts as follows:
2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37........
