# Only Partially Perfect?

A multiplicative perfect number is a positive integer $$n$$ who's divisors' product totals to $$n^2$$.

For example, the factors of $$22$$ are $$1,2,11,22,~~1\cdot2\cdot11\cdot22=484$$

Define the term partially-multiplicative perfect number as a positive integer who's divisor's product totals to $$n^{\frac{5}{2}}$$. Find the sum of the first 4 partially-multiplicative perfect numbers.
