Yes, they are relatively prime.
No, they are not relatively prime.
Yes, they are relatively prime.
19 is a prime number and so there are no two prime factors.
If the two numbers have no factors in common then they are relatively prime. 152 = 2 x 2 x 2 x 19 171 = 3 x 3 x 19. They both have 19 as a factor and therefore 152 and 171 are NOT relatively prime.
12 and 30 are not relatively prime because they have two common prime factors (2 and 3).
12 and 35 are NOT prime numbers.
Nine can only be relatively prime when compared to another number or set of numbers. 9 is relatively prime to 4, 9 is not relatively prime to 12.
No, they are not.

no, the GCF is 19.
Yes, 19 and 299 are relatively prime. Two numbers are considered relatively prime if their greatest common divisor (GCD) is 1. Since 19 is a prime number and does not divide 299, their GCD is indeed 1. Therefore, they share no common factors other than 1.
