Here we will discuss and show you how to figure out which number is a factor of 10, but not a multiple of 28.
The most common way to determine which number is a factor of 10, but not a multiple of 28, is to simply list the factors of 10 and the multiples of 28 so you can compare the two lists.
The answer to "Which number is a factor of 10, but not a multiple of 28?" would be all the numbers that are on the Factors of 10 list, but not on the Multiples of 28 list.
Factors of 10: 1, 2, 5, 10
Multiples of 28: 28, 56, 84, 112, 140...
Answer: 1, 2, 5, 10
Alternatively, you can figure out which number is a factor of 10, but not a multiple of 28, by dividing every factor of 10 by 28. The answer would be all the quotients that are not integers.
