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
l=list(map(int,input().split()))
d=math.sqrt(l[0]*l[1]*l[2])
l1=d/l[0]
l2=d/l[1]
l3=d/l[2]
print(int(4*(l1+l2+l3)))
