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

s1, s2, s3 = input().split()

a = math.sqrt(int(s1) * int(s3) / int(s2))
b = math.sqrt(int(s1) * int(s2) / int(s3))
c = math.sqrt(int(s3) * int(s2) / int(s1))

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