What is the Difference Between Prime and Co-prime Numbers?Ī prime number is a number that has exactly two factors, 1 and the number itself. For example, (6,35) is a set of co-prime numbers, although 6 and 35 are composite numbers. Co-prime numbers form a pair of numbers that may not necessarily be prime numbers. Our expert tutors conduct 2 or more live classes per week, at a pace that matches the child's learning needs.įAQs on Coprime Numbers What are Co-prime Numbers in Math?Ĭoprime numbers are those numbers that do not have any common factor other than 1. Our mission is to transform the way children learn math, to help them excel in school and competitive exams.

A prime number is co-prime with any other number that is not its multiple.Ĭuemath is one of the world's leading math learning platforms that offers LIVE 1-to-1 online math classes for grades K-12.

1 forms a co-prime pair with any other number.

Any two consecutive numbers are always co-prime.

Any two prime numbers are always co-prime.

For example, 12 and 35 are co-prime numbers, although, 12 and 35 are NOT prime numbers.

Co-prime numbers need not necessarily be prime numbers.

It can also be said that if the GCF of any two numbers is 1, those are co-prime numbers.

Two numbers are co-prime if their GCF is 1.

Here is Cuemath's online co-prime calculator for our ease. Try out forming more such pairs of co-prime numbers by yourself.

In the list of co-prime numbers from 1 to 100, there are many pairs that can be listed as co-prime numbers based on the above properties. There are multiple such combinations where 1 is the only common factor. Any two consecutive numbers have 1 as their common factor.Ĭonsider a few pairs of such numbers.

All pairs of two consecutive numbers are co-prime numbers.For example, 2 and 3, 5 and 7, 11 and 13, and so on. We can check any two prime numbers and get them as co-prime. Two prime numbers are always co-prime.For example, 5 and 9 are co-prime numbers. The sum of two co-prime numbers is always co-prime with their product.Two even numbers cannot be co-prime numbers as they always have 2 as the common factor.

1 forms a co-prime number pair with every number.

The Least Common Multiple (LCM) of two co-primes is always their product.

For example, 5 and 9 are coprime numbers, there, HCF (5, 9) = 1.

The Highest Common Factor (HCF) of two coprime numbers is always 1.

Co-prime numbers can be identified easily with the help of some properties that are explained below:
