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 = map(int, input().split())
a = int(((s1 * s3) / s2) ** 0.5)
b = int(((s1 * s2) / s3) ** 0.5)
c = int(((s2 * s3) / s1) ** 0.5)
print(4 * (a+b+c))
