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.

x, y, z = map(int, input().split())

a = ((x*z)/y)**0.5
b = ((x*y)/z)**0.5
c = ((y*z)/x)**0.5

print(int(a+b+c)*4)
