A prime number is a positive number that has exactly two factors, 1 and itself. Alternatively, you can think of a prime number as a number that is not the product of two smaller numbers. For example, 13 is a prime number because it can only be divided evenly by 1 and 13. For another example, 14 is not a prime number because it can be divided evenly by 1, 2, 7, and 14. The number one is not a prime number becuase it has only one factor, 1 itself.
