Yes, 77 and 51 are relatively prime. Two numbers are considered relatively prime if their greatest common divisor (GCD) is 1. The factors of 77 are 1, 7, 11, and 77, while the factors of 51 are 1, 3, 17, and 51. Since they share no common factors other than 1, their GCD is 1, confirming that they are relatively prime.
