Finally!!!

 Prime Number – a number that has only two factors, itself and is prime because the only numbers that will divide into it evenly are 1 and 7.

2, 3, 5, 7, 11, 13, 17, 19 Special Note: One is not a prime number.

 Composite number – a that has more than two factors. 8 The factors of 8 are 1, 2, 4, 8

6, 8, 9, 10, 12, 14, 15 Special Note: Every whole number from 2 on is either composite or prime.

Special Note: One is not a prime nor a composite number. It is not prime because it does not have exactly two different factors. It is not composite because it does not have more than 2 factors.
