# Prime numbers

## Prime number – A number that is divisible only by itself and 1.

**NOTE:**

1 is not a prime number

## Prime numbers: Up to 100

2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37, 41, 43, 47, 53, 59, 61, 67, 71, 73, 79, 83, 89 and 97

You can remember the values of the first six prime numbers (2, 3, 5, 7, 11, 13) by counting the number of letters in each of the following words:

Prime suspect because “My (2) dog (3) bites (5) several (7) K (1) G (1) B (1) men (3).”

And 2, 3, 5, 7, 11 and 13 are the first six prime numbers.

Or we can picture this as follows:

Prime suspect because “My dog bites several KGB men.”
