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 = map(int, input().split())
v2 = s1*s2*s3
print(int(4 * (math.sqrt(v2 / (s1 * s1)) + math.sqrt(v2 / (s2 * s2)) + math.sqrt(v2 / (s3 * s3)))))
