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.
def common(a,b,c):
    return ((a*b/c)**(1/2))
    
x,y,z=input().split()
x=int(x)
y=int(y)
z=int(z)
l=common(x,y,z)
b=common(y,z,x)
h=common(x,z,y)
print (int(4*(l+b+h)))
