Two numbers are relatively prime if the only factor they have in common is 1.
Example:
12 and 17 are relatively prime because they have only 1 as a common factor.
12 and 21 are not relatively prime because they have 1 and 3 as common factors.

Relatively Prime numbers are sets of two or more numbers having 1 as their greatest common factor (gcf). All even numbers have 2 as a common factor, so no even number is relatively prime with any other even number.
Two composite numbers may or may not be relatively prime, depending on their factors. Relatively prime numbers are sets of two or more numbers having 1 as their greatest common factor (gcf). All even numbers have 2 as a common factor, so no even number is relatively prime with any other even number.
No because they are both composite numbers that have more than two factors.
No. They have more than just the number 1 as common factors. They also have the number 7. Relatively prime numbers only share the number 1 as a common factor.
A single number cannot be relatively prime. Relatively prime means that two or more numbers do not have any factors in common other than 1, which is the same as saying that they do not have any prime factors in common. 2 and 14 are not relatively prime because both have 2 as a factor. 9 and 14 are relatively prime because they do not have any factors in common except 1. 14 and 98 are not relatively prime because both have 7 as a factor. 14 and 103 are relatively prime because they do not have any factors in common except 1.
