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
p=input()
a,d,c=map(int,p.split())
l=int(math.sqrt((a*c)/d))
b=int(math.sqrt((a*d)/c))
h=int(math.sqrt((c*d)/a))
print(4*(l+b+h))
