What Is a Prime Number

A prime is any whole and positive number that can NOT be divided into any positive divisor, except the number itself and 1 . So, for any prime number there are only two divisors, resulting a positive whole number. For more detailed information see what is a prime number and get a better idea.
Example:

5 is a prime number, because it has only 2 positive devisors - 1 and 5.
8 is NOT a prime number, because it can be divided by 2,4,8 and 1.
6 is NOT prime, because it can be divided by 1,2,3 and 6.
7 is prime, because it can be divided by only 1 and 7.
1 is NOT a prime number, because it can be devided by only 1 number - itself.

If a number is even, it will be hard for it to be prime, because it can always be divided by 2, except by itself and 1. So 2 is the only one prime number that is even.

All Prime Numbers up to 100

Here is their list (these are 25 numbers): 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
