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.
def lcm(n):
    res = 0
    if n == 1:
        print(1)
    elif n == 2:
        print(2)
    elif n % 2 == 0:
        if n % 3 == 0:
            res = (n - 1) * (n - 2) * (n - 3)
            print(res)
        else:
            res = n * (n - 1) * (n - 3)
            print(res)
    else:
        res = (n - 1) * (n - 2) * n
        print(res)
    return res

def main():
    num = int(input())
    lcm(num)

if __name__ == "__main__":
    main()
