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.
import math

a = list(map(int,list(input().split())))
suma = math.sqrt(a[0]/a[1] * a[2]) + math.sqrt(a[1]/a[2] * a[0]) + math.sqrt(a[2]/a[0] * a[1])
suma = 4*suma

print(int(suma))
