For example, 2 and 3 are two prime numbers. Factors of 2 are 1, 2, and factors of 3 are 1, 3. The only common factor is 1 and hence they are co-prime. Any two successive numbers/ integers are always co-prime: Take any consecutive numbers such as 2, 3, or 3, 4 or 5, 6, and so on; they have 1 as their HCF.,

## Is 18 and 35 a Coprime number?

Since both have only one common factor, i.e., 1, therefore, they are co-prime numbers.

## What is Coprime number?

Co-Prime Numbers are sets of Numbers that do not have any Common factor between them other than one. This means that their highest Common factor (HCF) is 1. There should be at least two Numbers in order to form Co-Primes. Co-Prime Numbers are also called relatively Prime Numbers.

## What is co-prime numbers with examples?

For example, 2 and 3 are two prime numbers. Factors of 2 are 1, 2, and factors of 3 are 1, 3. The only common factor is 1 and hence they are co-prime. Any two successive numbers/ integers are always co-prime: Take any consecutive numbers such as 2, 3, or 3, 4 or 5, 6, and so on; they have 1 as their HCF.
