## Prime Number | ## more ... |

A Prime Number can be divided evenly only by 1, or itself. And it must be a whole number greater than 1. Example: 5 can only be divided evenly by 1 or 5, so it is a prime number. But 6 can be divided evenly by 1, 2, 3 and 6 so it is NOT a prime number (it is a composite number). See: Composite Number | |
