Here we will discuss and show you how to figure out which number is a factor of 42, but not a multiple of 70.
The most common way to determine which number is a factor of 42, but not a multiple of 70, is to simply list the factors of 42 and the multiples of 70 so you can compare the two lists.
The answer to "Which number is a factor of 42, but not a multiple of 70?" would be all the numbers that are on the Factors of 42 list, but not on the Multiples of 70 list.
Factors of 42: 1, 2, 3, 6, 7, 14, 21, 42
Multiples of 70: 70, 140, 210, 280, 350...
Answer: 1, 2, 3, 6, 7, 14, 21, 42
Alternatively, you can figure out which number is a factor of 42, but not a multiple of 70, by dividing every factor of 42 by 70. The answer would be all the quotients that are not integers.
