## 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.

## Which are the Coprimes?

Co-prime Numbers. Co-prime numbers are pairs of numbers that do not have any common factor other than 1. There should be a minimum of two numbers to form a set of co-prime numbers. Such numbers have only 1 as their highest common factor, for example, {4 and 7}, {5, 7, 9} are co-prime numbers.

**What are the Coprimes of 12?**

There are 4 positive integers less than 12 and co- prime with 12. They are 1, 5, 7, and 11.

### Are 18 and 35 Coprime numbers?

## Is 31 and 93 a Coprime?

The factors of 31 are 1 and 31 and the factors of 93 are 1, 3 and 31. Here 31 and 93 have two common factors: they are 1 and 31. Hence, their HCF is 31 and they are not co-prime.

## Is 12 and 13 a Coprime?

Two integers are relatively prime (or coprime) if there is no integer greater than one that divides them both (that is, their greatest common divisor is one). For example, 12 and 13 are relatively prime, but 12 and 14 are not.

**Is 8 and 10 are Coprime?**
