Answer 1

Answer:

18 and 35

Step-by-step explanation:

18 and 35 have no common factors, Therefore 18 and 35 are coprime numbers. As they have no common factors, 15 and 37 are co-prime numbers. As they have a common factor - 5, hence 30 and 415 are not co-prime. As they have no common factors, 17 and 168 are coprime numbers.
