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())
ln,br,ht=0,0,0
for i in range(1,a//2+2):
	ln=i
	br=a/ln
	ht=b/ln
	if br*ht==c:
		break
ans=(4*ln+4*br+4*ht)
if ans.is_integer():
	print(int(ans))
