Here we will discuss and show you how to figure out which number is a factor of 40, but not a multiple of 8.
The most common way to determine which number is a factor of 40, but not a multiple of 8, is to simply list the factors of 40 and the multiples of 8 so you can compare the two lists.
The answer to "Which number is a factor of 40, but not a multiple of 8?" would be all the numbers that are on the Factors of 40 list, but not on the Multiples of 8 list.
Factors of 40: 1, 2, 4, 5, 8, 10, 20, 40
Multiples of 8: 8, 16, 24, 32, 40...
Answer: 1, 2, 4, 5, 10, 20
Alternatively, you can figure out which number is a factor of 40, but not a multiple of 8, by dividing every factor of 40 by 8. The answer would be all the quotients that are not integers.
