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
num1, num2, num3 = input().split(" ")
num1, num2, num3 = int(num1), int(num2), int(num3)
c = int(math.sqrt(num3*num2/num1))
a = int(num1/num2*c)
b = int(num2/c)
print(4*a + 4*b + 4*c)
