Here we will discuss and show you how to figure out which number is a factor of 39, but not a multiple of 79.
The most common way to determine which number is a factor of 39, but not a multiple of 79, is to simply list the factors of 39 and the multiples of 79 so you can compare the two lists.
The answer to "Which number is a factor of 39, but not a multiple of 79?" would be all the numbers that are on the Factors of 39 list, but not on the Multiples of 79 list.
Factors of 39: 1, 3, 13, 39
Multiples of 79: 79, 158, 237, 316, 395...
Answer: 1, 3, 13, 39
Alternatively, you can figure out which number is a factor of 39, but not a multiple of 79, by dividing every factor of 39 by 79. The answer would be all the quotients that are not integers.
