No, five is a prime number because there are only two whole numbers that when multiplied, equals five. (Those numbers are five and one.) In order for a number to be composite, it has to have factors other than itself and one.
A prime number is a number that is only divisible by one and itself. For example, the number five is a prime number, but its multiples are not because they are divisible by five. The prime numbers from one to twenty are 2, 3, 5, 7, 11, 13, 17, and 19. A composite number is the opposite of a prime number. A composite number can be divided by more numbers than just one and itself. The composite numbers from one to twenty are 4, 6, 8, 9, 10, 12, 14, 15, 16, 18, and 20. ~Jessica.Songbird
