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 = eval(input())
k=0
mlt = 1
while k < 3 and n > 0:
        if n % n-1 == 0:
                n=n-1
                continue
        mlt*=n
        n-=1
        k+=1
print(mlt)
