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

sq = int(math.sqrt(a1 * a2 * a3))

a = int(sq/a1)
b = int(sq/a2)
c = int(sq/a3)

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