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 = list(map(int, input().split(' ')))

z = math.sqrt((a[1] * a[2]) / a[0])
v = a[2] / z
u = a[0] / v

u, v, z = int(u), int(v), int(z)

print(4 * (u + v + z))
