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 as m
a1,a2,a3=map(int,input().split())
p=m.sqrt( (a1*a3)//a2 )
q=m.sqrt( (a2*a3)//a1 )
r=m.sqrt( (a1*a2)//a3 )
print(int(4*(p+q+r)))
