## What does Coprime mean?

A Co-prime number is a set of numbers or integers which have only 1 as their common factor i.e. their highest common factor (HCF) will be 1. Co-prime numbers are also known as relatively prime or mutually prime numbers. It is important that there should be two numbers in order to form co-primes.

## Is 25 a Coprime number?

18 and 25 have no common factor other than 1. Yes, (18,25) are coprime numbers.

## Which is Coprime number?

more … When two numbers have no common factors other than 1. In other words there is no whole number that you could divide them both by exactly (without any remainder).

## Are 15 and 18 Coprime numbers?

Common factors of 15 and 18 are 1 and 3. Since the given set of numbers have more than one factor as 3 other than factor as 1. So, 15 and 18 are not coprime numbers.
