Answer: A composite number can be divided into a whole number other than itself and one. A prime number can only be divided by itself and one.
Step-by-step explanation: Ex: 1,2,3,5,7,11,13, etc are prime. 4,6,8,9, etc are composite numbers. So... the first list is correct because 6 (3*2), 24(6*4), 51 (3*17), 105 (5*21) can all be multiplied by integers other than itself and one.
