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

in_faces = input().split()
faces = list(int(face) for face in in_faces)

a = math.sqrt((faces[0] * faces[1]) / faces[2])
b = math.sqrt((faces[1] * faces[2]) / faces[0])
c = math.sqrt((faces[0] * faces[2]) / faces[1])

faces_sum = a + b + c

print(int(faces_sum * 4))
