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())
import math as m
a = m.sqrt(x*z/y)
b = m.sqrt(x*y/z)
c = m.sqrt(y*z/x)
ans = int(4*(a+b+c))
print(ans)
