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.
l=list(map(int,input().split()))
a=l[0]/l[1]
x=(l[2]/a)**0.5
y=a*x
z=l[0]/y
an=(4*(x+y+z))
print(int(an))
