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