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.

a1,a2,a3= list(map(int,input().split()))

x= ((a1*a2)//a3)**0.5
y= ((a3*a2)//a1)**0.5
z= ((a1*a3)//a2)**0.5

p= 4*x + 4*y + 4*z
print(int(p))
