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.
from math import sqrt, ceil

s1, s2, s3 = map(int, input().split())
a = sqrt(s1 * s2 // s3)
b = sqrt(s3 * s1 // s2)
c = sqrt(s3 * s2 // s1)
print((a+b+c) * 4)
