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.

def tamanhoDoLado(a, b, c):
  ans = math.sqrt(a * b // c)
  return ans

def somaLados(a, b, c):
  ans = (a + b + c) * 4
  return ans


a, b, c = [int(i) for i in input().split()]
print(int(somaLados(tamanhoDoLado(a, b, c), tamanhoDoLado(a, c, b), tamanhoDoLado(b, c, a))))
