No.
21 = 3 x 7 39 = 3 x 13 So 21 and 39 are not relatively prime as they are sharing a common factor: 3
Yes, 15 and 21 are relatively prime because they have no common positive factors other than 1. The prime factorization of 15 is 3 and 5, while the prime factorization of 21 is 3 and 7. The only common factor is 3, which means they are not relatively prime.
Yes, they are relatively prime.
Yes, they are relatively prime.
Yes, they are relatively prime.
No, 14 and 21 are not relatively prime. They share the factor 7.No.
It can be. 21 is relatively prime with 32.
21 = 3 x 7 39 = 3 x 13 So 21 and 39 are not relatively prime as they are sharing a common factor: 3

Yes, they are relatively prime.
Yes, 4 and 21 are relatively prime. Numbers that are relatively prime only have the number 1 as a common factor. That is the case with 4 and 21.
Yes, they are relatively prime.
