    1 Answer

    1. Using prime factorization:
      • 242 = 2 × 11², with prime factors 2 and 11.
      • 195 = 3 × 5 × 13, with prime factors 3, 5, and 13.
      Since there are no common factors between the two sets of primes, the greatest common divisor (GCD) is 1. This confirms that 242 and 195 are co-prime, as they share no prime factors beyond the trivial case of 1.
