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 = input().split()
ar = list(map(int, a))
x = ar[0]*ar[1]*ar[2]
x = math.sqrt(x)
b = x/ar[0]
c = x/ar[1]
d = x/ar[2]
v = b + c + d
print(int(v*4))
