Yes!
Yes, they are relatively prime.
They are both not prime
Two numbers are relatively prime if their greatest common divisor (GCD) is 1. The GCD of 55 and 121 can be determined by their prime factorizations: 55 is 5 × 11, and 121 is 11 × 11. Since they share a common factor of 11, their GCD is 11, meaning 55 and 121 are not relatively prime.

They are both not prime
no
3.
Yes, 55 and 62 are relatively prime because they have no common factor greater than 1.
No.
No, their common factors are 1 and 11. As 1 is not their only common factor, then they are not relatively prime.
121, 169, 289
The greatest common factor of 21 and 121 is 1. (21 and 121 are relatively prime.)
