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
a1,a2,a3 = list(map(int,input().split()))    #1e4
a,b,c    = sqrt((a2*a3)/a1), sqrt((a1*a3)/a2), sqrt((a1*a2)/a3)
print(4*int(a+b+c))
