The definition of a prime is an integer that has two positive factors, one and itself. These are two distinct factors. One only has one positive factor. Thus it's not a prime.

True. By definition, a prime number is divisible by one and by itself. Also by definition, a perfect square has at least an additional pair of factors - it's square root. Therefore a prime number could never be a perfect square. One exception that might come to mind in this case is the number one. One however, is not considered a prime number, and thus does not conflict with this rule.
