For numbers to be relatively prime, there needs to be more than one of them.


What are the realitivly prime numbers?

Any number greater than one can be relatively prime. Two relatively prime numbers have a GCF of 1.


What are relatively prime numbers?

Numbers having no common positive divisors other than one are relatively prime. In other words, the greatest common denominator of the numbers is one. Example: 24 and 25 are relatively prime.


How can you use prime factorization to determine if two numbers are relatively prime?

Once your prime factorization is complete and you discover that there are no numbers in common, the GCF is one and the numbers are declared to be relatively prime.


What numbers have the greatest common factors of one?

Co-prime numbers, relatively prime numbers and any set of prime numbers.


What are all the composite numbers between 50 and 100 that are relatively prime?

A single number cannot be relatively prime. Any pair of numbers between 50 and 100 of which one is a prime will be relatively prime. There are 728 pairs of numbers that are relatively prime and I have neither the time nor patience to list them all!


Are 36 and168 relatively prime?

No even numbers are relatively prime because they all have the prime factor 2 as one of their factors.


Are 28 and 34 relatively prime?

No, 28 and 34 are not relatively prime. No pair of even numbers can be relatively prime, as they always share at least one factor (2).


What is a relatively prime number?

What are all the relatively prime numbers up to 50?

All of them. Any number greater than one can be relatively prime.

True or false if two numbers a relatively prime one of the must be prime?

False. Consider 4 and 9. Neither are prime, but they have no common factors other than 1 and are therefore relatively prime. More generally, any two numbers p^n and q^n where p, q both prime and n<>p or q and n>1 are relatively prime. This is by no means all pairs of relatively prime numbers, but it's an easy way to find examples where neither of the pair is prime.


How can you choose one number so that so that it will be relatively prime to any other number?

Relatively prime numbers have a GCF of 1.
