Question
Which of the following is a pair of
co-primes?Solution
To determine which of the given pairs of numbers are co-prime, we must check if their greatest common divisor (GCD) is 1. Let's evaluate each pair: (198, 175) : Prime factorization of 198: 198=2×32×11 Prime factorization of 175: 175=52×7 GCD (198, 175) = 1 (No common factors) This pair is co-prime.
