No. It depends on how good you are at arithmetic.
The greatest product you can achieve by multiplying a 3-digit number by a 1-digit number is 9720, which comes from multiplying 972 (the largest 3-digit number less than 1000 when divided by 9) by 9 (the largest 1-digit number). Thus, the factors are 972 and 9.
