Here we will discuss and show you how to figure out which number is a factor of 45, but not a multiple of 12.
The most common way to determine which number is a factor of 45, but not a multiple of 12, is to simply list the factors of 45 and the multiples of 12 so you can compare the two lists.
The answer to "Which number is a factor of 45, but not a multiple of 12?" would be all the numbers that are on the Factors of 45 list, but not on the Multiples of 12 list.
Factors of 45: 1, 3, 5, 9, 15, 45
Multiples of 12: 12, 24, 36, 48, 60...
Answer: 1, 3, 5, 9, 15, 45
Alternatively, you can figure out which number is a factor of 45, but not a multiple of 12, by dividing every factor of 45 by 12. The answer would be all the quotients that are not integers.
