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
data = input().split()

A1, A2, A3 = int(data[0]), int(data[1]), int(data[2])


H   =   int(math.sqrt((A2 * A3) // A1))
W   =   A3 // H
L   =   A1 // W


print(4*L + 4*W + 4*H)
