Well, honey, let me break it down for you. When you multiply a 4-digit number (ranging from 1000 to 9999) by a 1-digit number (ranging from 0 to 9), the result can be a 3-digit number (ranging from 0 to 8991). So no, the product of a 4-digit number and a 1-digit number is not always a 5-digit number. Math doesn't discriminate, darling.
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.
