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.
xy, yz, zx = map(int, input().split())
x = ((xy*zx)//(yz))**0.5
y = ((yz*xy)//(zx))**0.5
z = ((yz*zx)//(xy))**0.5
ans = (4*x) + (4*y) + (4*z)
print(int(ans))
