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

(x1,x2,x3)=[int(i) for i in input().split()]

c=sqrt(x2*x3/x1)

b=x2/c

a=x1/b

print(int(4*a+4*b+4*c))
