WebCoprime numbers are numbers that have only 1 as their HCF. (a) 18 and 35 18 and 35 have no common factors, Therefore, 18 and 35 are coprime numbers. (b) 15 and 37 As they have no common factors, 15 and 37 are co-prime numbers. (c) 30 and 415 As they have a common factor 5, hence, 30 and 415 are not co-prime. (d) 17 and 168 WebCorrect option is A) There is no common prime factor between two co-prime numbers. So, only common factor is 1 and it is the highest. Hence, HCF of two co-prime numbers is 1.
