A Prime number has just two positive integer factors, itself and 1. Therefore, 0 and 1, which have none, and one, positive integer factor respectively, are not prime.
A composite number has more than two positive integer factors - that is, including itself and 1. Therefore, since 0 and 1 do not have more than two positive integer factors, they are not composite, either.

What is the largest two digit number to the exactly 9 factors?
To have exactly 9 factors, the number would either have to have a prime number raised to the 8th. power; this is not possible with two digits.The other option is to have a prime number raised to the second power, times another prime number raised to the second power. (The number of factors in this case is (2 + 1)(2 + 1).) This is only possible if you use the prime factors 2 and 3; any other combination of prime numbers will yield a number that has more than 2 digits.
