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
lb, bh, hl = [int(x) for x in input().split()]
lbh = int(math.sqrt(lb * bh * hl))
l = lbh // bh
b = lbh // hl
h = lbh // lb
sum = 4 * (l + b + h)
print(sum)
