Eg1) 3 and 12 are not co prime (although 3 is a prime number) because there is a common factor 3 (apart from 1) between 3 and 12 Eg 2) 5 and 12 is coprime because there is no common factor between 5 and 12 except 1. 0 votes 0 votes kumar.dilip commented Jan 2, 2019 reply Follow Share BHOJARAM just remember GCD(x1,x) = 1. 0 votes 0 votes BHOJARAM commented Jan 2, 2019 reply Follow Share Thannx @kumar.dilip Nice trick 0 votes 0 votes Please log in or register to add a comment.
