There is a formula for finding the number of positive integer factors of a number. Take the factorization of the numberm say 2^6x3^4. Take the exponents (in this case, 6 and 4) and add one to each (7 and 5) and multiply them together, and you obtain the number of factors of the number. By this principle, only perfect fourth powers have 5 factors.
