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

arr = list(map(int, input().rstrip().split()))
t = 0
a = math.sqrt((arr[0]*arr[1]/arr[2]))
b = math.sqrt((arr[1]*arr[2]/arr[0]))
c = math.sqrt((arr[0]*arr[2]/arr[1]))
print(int((a+b+c)*4))
