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.

arr = list(map(int,input().split()))

b = int(math.sqrt((arr[1]*arr[0])/arr[2]))

a = arr[0]//b
c = arr[2]//a

ans = 4*(a+b+c)

print(ans)
