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

sides = list(map(int, input().strip().split()))

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

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