Here we will discuss and show you how to figure out which number is a factor of 15, but not a multiple of 5.
The most common way to determine which number is a factor of 15, but not a multiple of 5, is to simply list the factors of 15 and the multiples of 5 so you can compare the two lists.
The answer to "Which number is a factor of 15, but not a multiple of 5?" would be all the numbers that are on the Factors of 15 list, but not on the Multiples of 5 list.
Factors of 15: 1, 3, 5, 15
Multiples of 5: 5, 10, 15, 20, 25...
Answer: 1, 3
Alternatively, you can figure out which number is a factor of 15, but not a multiple of 5, by dividing every factor of 15 by 5. The answer would be all the quotients that are not integers.
