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.
a1, a2, a3 = [int(x) for x in input().split()]

from math import*

w = sqrt((a1/a3)*a2)
l = a2/w
h = a1/w

print(int(w*4 + l*4 + h*4))
