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.
s1, s2, s3 = list(map(int, input().split()))

a = (s1 * s2 / s3)**0.5
b = (s2 * s3 / s1)**0.5
c = (s3 * s1 / s2)**0.5

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