State whether the number 91 is prime, composite, or neither.

A prime number is an integer greater than zero, which has exactly two positive divisors. We can also define it as that positive integer that can not be expressed as a product of two positive integers smaller than it, or, as a product of two positive integers of more than one form. It should be noted that with either of the two definitions, 1 is excluded from the set of prime numbers.
