Here we will discuss and show you how to figure out which number is a factor of 99, but not a multiple of 9.
The most common way to determine which number is a factor of 99, but not a multiple of 9, is to simply list the factors of 99 and the multiples of 9 so you can compare the two lists.
The answer to "Which number is a factor of 99, but not a multiple of 9?" would be all the numbers that are on the Factors of 99 list, but not on the Multiples of 9 list.
Factors of 99: 1, 3, 9, 11, 33, 99
Multiples of 9: 9, 18, 27, 36, 45, 54...
Answer: 1, 3, 11, 33
Alternatively, you can figure out which number is a factor of 99, but not a multiple of 9, by dividing every factor of 99 by 9. The answer would be all the quotients that are not integers.
