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
s=input('')
a,b,c=s.split(' ')
x1=int(a)
x2=int(b)
x3=int(c)
a=math.sqrt((x1*x3)/x2)
b=math.sqrt((x1*x2)/x3)
c=math.sqrt((x2*x3)/x1)
print(int(4*a+4*b+4*c))
