Here we will discuss and show you how to figure out which number is a factor of 42, but not a multiple of 3.
The most common way to determine which number is a factor of 42, but not a multiple of 3, is to simply list the factors of 42 and the multiples of 3 so you can compare the two lists.
The answer to "Which number is a factor of 42, but not a multiple of 3?" would be all the numbers that are on the Factors of 42 list, but not on the Multiples of 3 list.
Factors of 42: 1, 2, 3, 6, 7, 14, 21, 42
Multiples of 3: 3, 6, 9, 12, 15, 18...
Answer: 1, 2, 7, 14
Alternatively, you can figure out which number is a factor of 42, but not a multiple of 3, by dividing every factor of 42 by 3. The answer would be all the quotients that are not integers.
