Co-prime numbers, also known as relatively prime numbers, are pairs of numbers that have no common factors other than 1. For example, the pairs (8, 15) and (9, 28) are co-prime because their greatest common divisor (GCD) is 1. In the range from 1 to 200, many co-prime pairs exist, such as (14, 25), (20, 33), and (99, 100). Essentially, any two prime numbers are co-prime, as well as any two numbers that do not share any prime factors.
