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.
a,b,c=map(int, input().split())
temp1=int(a/b*c)
temp2=int(b/c*a)
temp3=int(c/a*b)
print(4*int(temp1**0.5 +temp2**0.5 +temp3**0.5))
