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
a=[]
a=list(map(int,input().split()))
ab=a[0]
bc=a[1]
ca=a[2]
c=math.sqrt(ca/(ab/bc))
b=math.sqrt(ab/(ca/bc))
a=math.sqrt(ab/(bc/ca))
print(int(4*(a+b+c)))
