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.
areas = [int(i) for i in input().split(" ")]

xy = areas[0]
yz = areas[1]
zx = areas[2]

x = ((xy * zx) / yz)**(1/2)
y = xy / x
z = zx / x

sum_of_edges = int(x*4 + y*4 + z*4)
print(sum_of_edges)
