Question

what are co-prime numbers and composite numbers..state with exmples.

Answer 1

Coprime numbers are numbers which do not have a common factor other than 1

Example 8 = 2³*1

9 = 3² * 1

Here only one is common

Remember that consecutive numbers(numbers coming one after another ) are Coprime

Composite number are numbers which have more than 2 factors

Example, The factors of 6 are 1,2,3,6

It has more than 2 factors

Hence it is a composite number

Answer 2

co-prime numbers are two which have only 1 as a common factor for example; 2,3,5,7etc

And composite numbers are those which are product of primes and have more than one factor for example; 6 we can also wrote 6 as 2×3 like this 8,9,10
