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.
a, b, c = list(map(int, input().split()))

import math

x = math.sqrt(1.0 * a * b / c)
y = math.sqrt(1.0 * a * c / b)
z = math.sqrt(1.0 * c * b / a)

# print(x, y, z)

print(int(4 * (x + y + z)))
