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

area1, area2, area3 = map(int,input().split(' '))

side1 = math.sqrt(area1 * area2 // area3)
side2 = area1 / side1
side3 = area2 / side1

print(int(side1 + side2 + side3) * 4)
