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 = list(map(int, input().split()))
q = ab*(bc+ac) + bc*(ac + ab) + ac*(ab+bc)

a = math.sqrt((2*ab*ac)*(ac+ab)/(q-2*ab*ac))
b = ab/a
c = ac/a
ans = 4*(a+b+c)
print(int(ans))
