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.
a, b, c = map(int, input().split())

s1 = (a * b / c) ** (1 / 2)
s2 = (a * c / b) ** (1 / 2)
s3 = (b * c / a) ** (1 / 2) 

print(4 * int((s1 + s2 + s3)))
