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.
n = input().split()
a_c = int(n[0])
a_b = int(n[1])
b_c = int(n[2])
c = (a_c / a_b * b_c) ** 0.5
a = a_c / c
b = a_b / a
print(int(4 * a + 4 * b + 4 * c))
