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
x12, x13, x23 = [int(s) for s in input().split()]
x1 = math.sqrt(x12*x13/x23)
x2 = x12 / x1
x3 = x13 / x1
print(int(4*(x1+x2+x3)))
