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.
side_area = list(map(int, input().split()))
s1 = side_area[0]
s2 = side_area[1]
s3 = side_area[2]
a = (s1*s2/s3)**(0.5)
b = (s1*s3/s2)**(0.5)
c = (s3*s2/s1)**(0.5)
print(int(4*(a+b+c)))
