9 is a composite number. Prime numbers cannot be divided by anything but 1 and the number itself. In another form, prime numbers have two factors - 1 and the number itself. The factors of 9 are: 3 (3x3), 9 (9x1), 1 (1x9) Therefore, since there is three as a factor besides 1 and the number itself, 9 is not prime. It's composite.9 Is an composite number. :)
