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
a,b,c=map(int,input().split())
x=sqrt((a*b)//c)
y=sqrt((b*c)//a)
z=sqrt((c*a)//b)
print(4*int(x+y+z))
