# --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 asp(n)= σ(n)n . Find the sum of all positive integers n ≤ 1018 for which p(n) has the form k + 1⁄2, where k is an integer.

assert.strictEqual(euler241(), 482316491800641150);
