Here we will discuss and show you how to figure out which number is a factor of 39, but not a multiple of 31.
The most common way to determine which number is a factor of 39, but not a multiple of 31, is to simply list the factors of 39 and the multiples of 31 so you can compare the two lists.
The answer to "Which number is a factor of 39, but not a multiple of 31?" would be all the numbers that are on the Factors of 39 list, but not on the Multiples of 31 list.
Factors of 39: 1, 3, 13, 39
Multiples of 31: 31, 62, 93, 124, 155...
Answer: 1, 3, 13, 39
Alternatively, you can figure out which number is a factor of 39, but not a multiple of 31, by dividing every factor of 39 by 31. The answer would be all the quotients that are not integers.
