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, ac, bc = [int(x) for x in input().split()]

b = math.sqrt(bc * ab / ac)
a = ab / b
c = ac / a

s = 4*a + 4*b + 4*c
print(int(s))
