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
a1, a2, a3 = [int(x) for x in input().split()]

e1 = math.sqrt(a2 * a3 / a1);
e2 = math.sqrt(a3 * a1 / a2);
e3 = math.sqrt(a1 * a2 / a3);

print(4 * int(e1 + e2 + e3));
