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.
from math import sqrt
a = [int(x) for x in input().split()] 

l = sqrt((a[0]/a[1])*a[2])
b = sqrt((a[1]/a[2])*a[0])
h = sqrt((a[2]/a[0])*a[1])

print(int(4*(l+b+h)))
