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
n,m,o=list(map(int,input().split()))
a=math.sqrt(n*m/o)
b=math.sqrt(o*n/m)
c=math.sqrt(o*m/n) 
s1=a+b+c
print(round(s1*4))
