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.
import math

def sum_of_edges(a, b, c):
    common_area = math.sqrt(a * b / c)
    edge1 = int(math.sqrt(a * c / b))
    edge2 = int(math.sqrt(b * c / a))
    return 4 * (edge1 + edge2 + common_area)

# Read input
a, b, c = map(int, input().split())

# Calculate and print the sum of all edges of the parallelepiped
print(sum_of_edges(a, b, c))
