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 = map(int,input().split())
a = ((a3*a1)//(a3+a2))*4 + ((a2*a1)//(a1+a3))*4+((a3*a2)//(a1+a2))*4
if a1==a2==a3:
	print(a1*4+a2*4+a3*4)
else:
	print(a)
