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
x ,y,z=list(map(int ,input().split()))

ans= 4 *(math.sqrt((x*y)/z) + math.sqrt((x*z)/y) +math.sqrt((z*y)/x)  )

print(int(ans))
