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.
## solution for a20j_35
import math
s=input().split()
a=[int(e) for e in s]
z=math.sqrt(a[2]*a[1]/a[0])
x=a[0]*z/a[1]
y=a[1]/z
print(4*(x+y+z))
