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.
## let the sides a,b and c
import math
sides = list(map(int,input().split()))
b = math.sqrt((sides[0]*sides[1])/sides[2])
a = sides[0]/b
c = sides[1]/b
res = int(4*a + 4*b + 4*c)
print(res)
