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

A1, A2, A3 = [int(j) for j in input().split()]

a = math.sqrt((A1*A2)/A3)
b = math.sqrt((A1*A3)/A2)
c = math.sqrt((A2*A3)/A1)

print(int(4*a + 4*b + 4*c))
