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.
[s1,s2,s3] = list(map(int,input().split()))

import math

val = (s3*s2)/s1

b = math.pow(val,0.5)
c = s3/b
a = s2/b

ans = 4*a + 4*b + 4*c

print(int(ans))
