## Is 18 and 25 are Coprime numbers?

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.

## What is Coprime number?

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.

## Are 4 and 9 relatively prime?

The only common divisor between 4 and 9 is number 1, so 4 and 9 are “prime with respect to each other”. Regarding the number 15 and 21, they are not relatively primes, since besides number 1 they also have number 3 as a common divisor.

## Is 12 a Coprime number?

Two successive integers are always coprime. For eg: (2,3), (11,12), (99,100) and so on; they have 1 as their HCF.

## Is 30 and 415 are co prime?

30 and 415 are not co-prime because 1 is not the only common factor of these numbers. Example, 5 is another common factor of 30 and 415. 17 and 68 are not co-prime because 1 is not the only common factor of these numbers.
