Some days ago, I learned the concept of LCM (least common multiple). I've played with it for several times and I want to make a big number with it.

But I also don't want to use many numbers, so I'll choose three positive integers (they don't have to be distinct) which are not greater than *n*. Can you help me to find the maximum possible least common multiple of these three integers?
The first line contains an integer *n* (1 ≤ *n* ≤ 10<sup class="upper-index">6</sup>) — the *n* mentioned in the statement.
n=int(input())
if(n<=6):
	if(n==1):
		print(1)
	elif(n==2):
		print(2)
	elif(n==3):
		print(6)
	elif(n==4):
		print(12)
	elif(n==5):
		print(60)
	elif(n==6):
		print(60)
if(n%2!=0):
	print(n*(n-1)*(n-2))
elif(n%2==0):
	k=round(n/2)
	print((n-1)*(n-2)*(n-3))
	#print(max(   (2*k*(k-1)*(k+k-1))  ,   (2*((2*k)-3)*(k-1)*(k+k-1)   ))
