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
l=map(int,raw_input().split())
a1=int(l[0])
a2=int(l[1])
a3=int(l[2])
a1=int(a1)
a2=int(a2)
a3=int(a3)
v=m.sqrt(a1*a2*a3)
c=int(v/a1)
b=int(v/a3) 
a=int(v/a2)
print(4*(a+b+c))
