You've got a rectangular parallelepiped with integer edge lengths. You know the areas of its three faces that have a common vertex. Your task is to find the sum of lengths of all 12 edges of this parallelepiped.
The first and the single line contains three space-separated integers — the areas of the parallelepiped's faces. The area's values are positive ( &gt; 0) and do not exceed 10<sup class="upper-index">4</sup>. It is guaranteed that there exists at least one parallelepiped that satisfies the problem statement.
from math import sqrt

A,B,C = map(int,input().split()) # A => ab,       B => bc,       C => ca
a = sqrt((A*C)/B)
b = sqrt((B*A)/C)
c = sqrt((C*B)/A)

print(int(4*(a+b+c)))
