The Greatest Common Divisor (GCD) for 3 15 is 3.
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.
