no, the GCF is 19.
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.
No. 152 is even and 171 is divisible by 3. A number is either prime or it isn't, the word relatively cannot be used here.
No. They are both composite numbers. They are not relatively prime either.
The GCF is 19.
1 and 171 171 is prime
No.
152 = 2x2x2x19.2,2,2,19
