It depends on whether 1 is considered a factor. If yes, then the answer to the question is no, since 1 and the number itself are the two factors implying that it is a prime. If 1 is not considered as a factor, then the square of any prime meets the requirements. If p is a prime, then p and p2 are the only two factors of p2.
