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.
x, y, z = map(int, input().split())

a = int((x * z / y) ** (1/2))
b = int((x * y / z) ** (1/2))
c = int((y * z / x) ** (1/2))

total = 4 * (a + b + c)
print(total)
