Additionally, we can state that a set of numbers is coprime if their highest common factor HCF is 1. When a pair of numbers have a common factor of 1, the two numbers are called coprime numbers. Remember that two numbers do not have to be prime numbers to be coprime numbers. Coprime numbers can also be composite numbers a number with more than two factors if their common factor is 1. According to the definition of coprime numbers, the provided set of numbers will be coprime if there is only one common factor between them, which is 1.

Which of the following are coprime

Co-prime numbers are a pair of numbers that have no common factor other than 1. Relatively prime or mutually prime numbers are other names for co-prime numbers. The HCF of co-prime numbers is 1, making 1 their only common factor. We can write each number along with 1 as a co-prime pair. Co prime pairs with numbers , starting from 1 are listed in the table below :. A pair of integers is co-prime if there is no other positive integer other than 1 that can divide them both. For instance, 21 and Here, 21 and 22 only share a single factor, which is 1. Since they are co-prime, their HCF equals 1. Here, the numbers 1 and 5 are two factors that 21 and 27 both share.
