Which are co primes?
Co-prime numbers are the numbers whose common factor is only 1. Such numbers have only 1 as their highest common factor, for example, {4 and 7}, {5, 7, 9} are co-prime numbers. Co-prime numbers need not be prime numbers always. Two composite numbers like 4 and 9 also form a pair of co-primes.
Are the numbers 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.
What are co primes give an example?
Co-prime Numbers. Co-prime numbers are the numbers whose common factor is only 1. There should be a minimum of two numbers to form a set of co-prime numbers. Such numbers have only 1 as their highest common factor, for example, {4 and 7}, {5, 7, 9} are co-prime numbers.
What are the prime factors of 9?
