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
from math import sqrt

a,b,c = list(map(int,input().split()))


a1 = sqrt((a*b)/c)
b1 = sqrt((b*c)/a)
c1 = sqrt((c*a)/b)


print(int(4*(a1+b1+c1)))
