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.
ars = list(map(int,input().split()))
s = []

for i in range(ars[0]+1):
	for j in range(ars[1]+1):
		if i*j == ars[0]:
			s.append((i,j))

for x,y in s:
	for k in range(1,ars[2]+1):
		if x*k == ars[1] and y*k == ars[2]:
			print( (x+y+k)*4)
			exit(0)
