Answer 2

Co- prime numbers are the pairs of Numbers if the only positive integer or factor that divides both of them is only 1. which gives set of numbers as 1, 2, 4 as factors of both numbers. So, apart from 1 they have 2 and 4 as common factors. Hence, we can say that 8 and 20 are not coprime.Is 25 a Coprime number?

Two integers a and b are said to be coprimes if they have no common factors other than 1 and the number itself. ... 18 and 25 have no common factor other than 1. =>HCF(18,25)=1. Yes, (18,25) are coprime numbers.
