Question

which of the following are co-prime e.g. ( 15 and 37 ) ​

Answer 1

Hey there

Co prime no.s are the no.s whose HCF is 1.

For example as you have stated rightly 15 and 37 do not have any other common factor other than 1 thus they are co prime. Moreover do remember that any two consecutive no.s are also co prime.
