Here we will discuss and show you how to figure out which number is a factor of 85, but not a multiple of 13.
The most common way to determine which number is a factor of 85, but not a multiple of 13, is to simply list the factors of 85 and the multiples of 13 so you can compare the two lists.
The answer to "Which number is a factor of 85, but not a multiple of 13?" would be all the numbers that are on the Factors of 85 list, but not on the Multiples of 13 list.
Factors of 85: 1, 5, 17, 85
Multiples of 13: 13, 26, 39, 52, 65, 78, 91...
Answer: 1, 5, 17, 85
Alternatively, you can figure out which number is a factor of 85, but not a multiple of 13, by dividing every factor of 85 by 13. The answer would be all the quotients that are not integers.
