The largest one digit number that has three factors is 9. Its factors are 1, 3, and 9.
It is 9999 (if a one is added, it becomes a five digit number: 9999 + 1 = 10,000)
You could say -9 or 0 for the smallest, depending on whether you want to include negative numbers or not. 9 would be the largest one digit number.
Two versions of this question have been merged ... the one that asks forthe smallest 5-digit number, and the one that asks for the largest.If we're talking integers (whole numbers), then-- the largest 5-digit number with no repeating digits is 98,765 .-- the smallest one is 10,234 .-- If decimals are included, then the largest number is the same,but the smallest one is .01234 .
4 : with factors 1, 2 and 4
Divide the 2-digit number by the 1-digit number. If the quotient comes out a whole number, then the big one is a multiple of the small one.
9 and 99
99 + 9 = 108

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.
