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.

i = int
cin = input
le = len
s = str
from math import sqrt

d1, d2, d3 = map(i, cin().split())

a, b, c = sqrt((d1 * d3) / d2), sqrt((d2 * d3) / d1), sqrt((d1 * d2) / d3)
                
print(4 * (a + b + c))
