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
ab,bc,ac=map(int,input().split())
x1,x2,x3=ab/bc,bc/ac,ab/ac
a=math.sqrt(x1/x2*bc)
b=math.sqrt(x2*x3*ac)
c=math.sqrt(ab/x1/x3)
jam=(4*(a+b+c))
if int(jam)==jam:
    print(int(jam))
else:
    print(int(jam)+1)
