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
ar = []
for i in input().split(' '):
    ar.append(int(i))
b = math.sqrt((ar[0]*ar[1])/ar[2])
a = ar[0]/b
c = ar[2]/a
print(int(4*(a+b+c)))
