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

a, b, c = [int(x) for x in input().split()]
x = math.sqrt((a*b)/c)
y = math.sqrt((a*c)/b)
z = math.sqrt((c*b)/a)
print((x+y+z)*4)
