No. Two even numbers cannot be relatively prime.
No.
120 and 49
No, 3 is a factor of both. Note that the digits of 120 add up to 3 and those of 147 add up to 12. Both are multiples of 3 so the numbers 120 s and 147 are divisible by 3 and not relatively prime

No, they are not relatively prime.
Can't be, they're both even numbers so must have a common factor of 2...
It can be. 34 is relatively prime to 35. 34 is not relatively prime to 40.
