Any two prime numbers will be relatively prime. Numbers are relatively prime if they do not have any prime factors in common. Prime numbers have only themselves as prime factors, so all prime numbers are relatively prime to the others.

Infinitely many numbers are relatively prime to 37. Because 37 is a prime number, all other numbers are relatively prime to it.

No, they are not relatively prime.

No, they are not relatively prime.

No, they are not relatively prime.

It is, and always is relatively prime.

Any two different prime numbers are relatively prime because relatively prime numbers are sets of two or more numbers having 1 as their greatest common factor.

Find their GCF.

Use the prime factorizations to determine the GCF. If the GCF is 1, the numbers are relatively prime. If the two numbers have no prime factors in common, they are relatively prime.

Two numbers are considered relatively prime when their GCF is 1.
