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

f = list(map(int, input().split()))

a =math.sqrt((f[0]*f[1])/f[2])
b = math.sqrt((f[1]*f[2])/f[0])
c = math.sqrt((f[2]*f[0])/f[1])

print(int(4*(a+b+c)))
