--description--

For a positive integer n, let σ(n) be the sum of all divisors of n, so e.g. σ(6) = 1 + 2 + 3 + 6 = 12.

A perfect number, as you probably know, is a number with σ(n) = 2n.

Let us define the perfection quotient of a positive integer as p(n) = \frac{σ(n)}{n}.

Find the sum of all positive integers n ≤ {10}^{18} for which p(n) has the form k + \frac{1}{2}, where k is an integer.
