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 main():
    x = [0] * 3
    a, b, c = map(int, input().split())
    x[0] = math.sqrt(a*b/c)
    x[1] = math.sqrt(c*a/b)
    x[2] = math.sqrt(c*b/a)

    print(sum(x)*4)
