What is the smallest positive integer that has exactly $2$ perfect square divisors? Answer by greenestamps(13198) (Show Source):
The two smallest perfect squares are 1 and 4, so the smallest positive integer that has exactly 2 perfect square divisors is the least common multiple of 1 and 4, which is, trivially, 4.
