Two of the three pairs are not but the triad is.

Yes, they are relatively prime.
No, they are not.
first you do the prime factorization 65 and 91.Then with the answers you get idk wat to do with them sry
The factors of 91 are: 1 7 13 91 The prime factors are: 7 and 13
65 + 91 = 156
Well, honey, the greatest common factor of 91, 78, and 65 is 13. It's like finding the biggest slice of cake that all three numbers can share without any leftovers. So, go ahead and divide those numbers by 13 and make sure everyone gets their fair share.
The factors of 65 are: 1, 5, 13, 65 The factors of 91 are: 1, 7, 13, 91
91
It's 13 because 65: 1, 5, 13, 65 91: 1, 7, 13, 91
65/91 = 5/7
The GCF is 13.
