Here we will discuss and show you how to figure out which number is a factor of 81, but not a multiple of 54.
The most common way to determine which number is a factor of 81, but not a multiple of 54, is to simply list the factors of 81 and the multiples of 54 so you can compare the two lists.
The answer to "Which number is a factor of 81, but not a multiple of 54?" would be all the numbers that are on the Factors of 81 list, but not on the Multiples of 54 list.
Factors of 81: 1, 3, 9, 27, 81
Multiples of 54: 54, 108, 162, 216, 270...
Answer: 1, 3, 9, 27, 81
Alternatively, you can figure out which number is a factor of 81, but not a multiple of 54, by dividing every factor of 81 by 54. The answer would be all the quotients that are not integers.
