Which pair of numbers is relatively prime? 12 and 81, 12 and 35, 12 and 32, 12 and 27

12 and 35 relatively prime

Step-by-step explanation:

Two integers are relatively prime if the only number that goes into both numbers is 1

12 and 81 are both divisible by 3 so the are not relatively prime

12/3 = 4 and 81 / 3 is 27

12 and 35 relatively prime

12 and 32 are both divisible by 4

12/4 = 3 and 32/4 = 8

12 and 27 are both divisible by 3

12/3 = 4 27/3 = 9

I agree with answer above
