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

product = int(math.sqrt(a1*a2*a3))
a, b, c = product//a1, product//a2, product//a3
print(4*(a+b+c))
