Actually a prime number is one that has only itself and 1 as a factor
1 x 1
1 x 2
1 x 3
1 x 5
1 x 7
1 x 11
1 x 13
1 x 17
1 x 19 for a few examples
4 is not a prime number because 2 x 2 = 4
6 is not a prime number because 2 x 3 = 6
8 is not a prime number because 4 x 2 or 2 x 2 x 2 = 8
10 is not a prime number because 2 x 5 = 10
AND so it goes. BTW: A FACTOR is a number that is multiplied by another FACTOR to get a PRODUCT (so we are talking about multiplication).
