Here we will discuss and show you how to figure out which number is a factor of 77, but not a multiple of 45.
The most common way to determine which number is a factor of 77, but not a multiple of 45, is to simply list the factors of 77 and the multiples of 45 so you can compare the two lists.
The answer to "Which number is a factor of 77, but not a multiple of 45?" would be all the numbers that are on the Factors of 77 list, but not on the Multiples of 45 list.
Factors of 77: 1, 7, 11, 77
Multiples of 45: 45, 90, 135, 180, 225...
Answer: 1, 7, 11, 77
Alternatively, you can figure out which number is a factor of 77, but not a multiple of 45, by dividing every factor of 77 by 45. The answer would be all the quotients that are not integers.
