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
a, b, c = input().split()
a, b, c = int(a), int(b), int(c)
a1 = math.sqrt(a * b / c) 
b1 = math.sqrt(c * a / b) 
c1 = math.sqrt(c * b / a) 
print(int(a1*4 + b1*4 + c1*4))
