26 greatest factor is itself, 19 is a prime number so it is 19...they dont have a same common factor but 26 x 19 is 494...
the answer is 1. 23 is a prime number, and the only factors of 26 are 13 and 2.
5 is a prime number. Neither 13 nor 26 are multiples of 5, so the only factor common to them all is 1.
The smallest prime factor of 26 is two.
The GCF of 26 and 65 is 13. 13 is a prime number. "Relatively prime" refers to numbers whose GCF is 1.
Since 17 is a prime number, the only positive integer common factor of 17 and 26 is 1.

26 = 2 * 13
No, it is not. The prime factors of 26 are 2and 13.
No. They have a common factor, 13. 26 = 13 x 2 65 = 13 x 5 Numbers are relatively prime if they have no common factors other than 1, i.e. that they have no prime number factors in common.
