Here we will discuss and show you how to figure out which number is a factor of 2, but not a multiple of 81.
The most common way to determine which number is a factor of 2, but not a multiple of 81, is to simply list the factors of 2 and the multiples of 81 so you can compare the two lists.
The answer to "Which number is a factor of 2, but not a multiple of 81?" would be all the numbers that are on the Factors of 2 list, but not on the Multiples of 81 list.
Factors of 2: 1, 2
Multiples of 81: 81, 162, 243, 324, 405...
Answer: 1, 2
Alternatively, you can figure out which number is a factor of 2, but not a multiple of 81, by dividing every factor of 2 by 81. The answer would be all the quotients that are not integers.
