Yes, 24 and 77 are relatively prime.
No, they are not relatively prime.
No, 77 adn 791 are not relatively prime; 7 is a common factor of 77 and 791No.
No.
No, they are not.
No, they are not relatively prime.
As 77 = 7 x 11, any number that is not a multiple of 7 or 11 is relatively prime to 77, e.g. 25, 38, 123
No.
Yes, they are relatively prime.
no
No, 60 and 75 are not relatively prime because their greatest common factor is 15 and not 1. In order for them to be relatively prime, 1 must be their greatest common factor.
You find their factors and compare them to see which ones are in common. The factors of 27 are 1, 3, 9 and 27. The factors of 77 are 1, 7, 11 and 77. The only common factor they have is 1. Therefore they are relatively prime.
