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.
from math import sqrt
A, B, C = input().split()

a, b, c = int(A), int(B), int(C)

x = sqrt((a*b)/c)

y = b/x

z  = c/y
# 
# print('x:{}, y:{}, z:{}'.format(x, y, z))
print(int(4*x + 4*y + 4*z))
