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