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
x,y,z=input().split(' ')
x,y,z=int(x),int(y),int(z)

a=sqrt(x*y/z)
b=y/a
c=x/a

answer=4*(a+b+c)

print(int(answer))
