# Are 16 and 45 coprime numbers?

Looking for an answer to the question: Are 16 and 45 coprime numbers? On this page, we have gathered for you the most accurate and comprehensive information that will fully answer the question: Are 16 and 45 coprime numbers?

GCD (16,56,85) = 1, so integers 16, 56 and 85 are coprime numbers. GCD (22,143,55) = 8, so integers 22, 143 and 55 are not coprime numbers. In this method, we factorize the integers and statue they are coprime if they have no common prime factor.

Factors of 18 are 1, 2, 3, 6, 9 and 18. 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. Some of the properties of co-prime numbers are as follows. 1 is coprime with every number.

1 is coprime with every number. As every prime number has only two factors 1 and the number itself, the only common factor of two prime numbers will be 1. For example, 11 and 17 are two prime numbers. Factors of 11 are 1, 11 and factors of 17 are 1, 17. The only common factor is 1 and hence is co-prime.

15 and 63 do not have a common prime factor so they are coprime numbers. In contrast, 15 and 50 are not coprime numbers because they have a common prime factor which is 5! The above definition, can be generalized to 3, 4, 5... N integers. So, integers are said to be coprime if their GCD is equal to 1. Equivalently, they have no common prime factor.

## Are 16 and 81 Coprime numbers?

Factors of 81 are 1, 3, 9, 27 and 81. Therefore, 1 is the only common factor of 81 and 16 which means that 81 and 16 are co-prime.

Here, we can see that 2 is a common prime factor between 18 and 16. So, the second pair 18, 16 are not coprime numbers.

## What is meant by Coprime?

In number theory, two integers a and b are coprime, relatively prime or mutually prime if the only positive integer that is a divisor of both of them is 1. Consequently, any prime number that divides a does not divide b, and vice versa.

## Which of the following are co-prime?

Coprime numbers are numbers that have only 1 as their HCF. 18 and 35 have no common factors, Therefore, 18 and 35 are coprime numbers. As they have no common factors, 15 and 37 are co-prime numbers. As they have a common factor 5, hence, 30 and 415 are not co-prime.

## What is Coprime number?

Co prime numbers are those numbers that have only one common factor, namely 1. That means a pair of numbers are said to be co prime when they have their highest common factor as 1. There are different ways to define co-prime numbers.

## What are the factors of 16?

Therefore, the factors of 16 are 1, 2, 4, 8, and 16 and the prime factorization of 16 is 16 = 2 × 2 × 2 × 2.

## How do you find a Coprime number?

To find the co-prime of a number, find the factors of the number first. Then, choose any number and find the factors of the chosen number. All the numbers which do not have any common factor other than 1 will be the co-prime of the given number.

## What do you mean by co-prime?

From Wikipedia, the free encyclopedia. In number theory, two integers a and b are coprime, relatively prime or mutually prime if the only positive integer that is a divisor of both of them is 1. Consequently, any prime number that divides a does not divide b, and vice versa.

## What is the LCM of the co-prime numbers 15 and 16?

240 Hence, the LCM of 15 and 16 by prime factorization is 240.

## Are 16 and 21 co Coprime numbers?

As visible, there are no common prime factors between 16 and 21, i.e. they are coprime. Hence, the HCF of 16 and 21 will be 1.

## Are Coprime numbers 81 and 16?

For example: The factors of 81 are 1, 3, 9, 27 and 81. The factors of 16 are 1, 2, 4, 8 and 16. The only common factor among them is 1. Hence, they are co-prime.
