It is: 8
Take the smallest 6-digit even number, then subtract one from it.
Largest three digit number is 999 and we see that it is odd. One less than that is 998 and it is even and it is also three digits. No other 3 digit number is larger than 998 while being even.
9 and 99
99 + 9 = 108
9
The largest one digit number that has three factors is 9. Its factors are 1, 3, and 9.
The largest six-digit number is 999,999. It is the highest value that can be represented with six digits, where each digit is at its maximum of 9. This number is one less than one million, which is the smallest seven-digit number.
It is 9999 (if a one is added, it becomes a five digit number: 9999 + 1 = 10,000)

2, is the only one-digit even number that is a prime number.
The largest single digit composite number is 9. The largest prime number is 17 million digits long. The definition of a composite number is any number that has at least one positive divisor other than one or the number itself (it is not a prime number). The largest composite digit is therefore longer than the largest prime number by at leaf +1.
