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
[a1,a2,a3] = list(map(int,input().split()))

l = math.sqrt(a1*a3/a2)

b = math.sqrt(a1*a2/a3)

h = math.sqrt(a2*a3/a1)

print(int(4*(l+b+h)))
