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
A1, A2, A3 = map(int, input().split())
a2 = math.sqrt((A1*A2)//A3)
a1 = A1//a2
a3 = A2//a2
print(int(4*(a1+a2+a3)))
