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.

ins = list(map(int, input().split(" ")))

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

ins[0], ins[1] = int(ins[0]), int(ins[1])

print(4 * sum(ins))
