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.
It can be. 26 is relatively prime to 27. 26 is not relatively prime to 34.
No, they are not relatively prime.
Yes.
Yes.
Prime number of 13 is 13 Prime numbers of 26 are 2 and 13 Prime numbers of 65 are 5 and 13 LCM = 2*5*13 =130
The GCF of 26 and 65 is 13. 13 is a prime number. "Relatively prime" refers to numbers whose GCF is 1.
No, 50 and 65 are not relatively prime.
It can be. 26 is relatively prime to 27. 26 is not relatively prime to 34.
No, they are not relatively prime.
The GCF of 9 and 26 is 1. 9 and 26 are relatively prime.
No.
Yes, they are relatively prime.
No, 65 and 70 are not relatively prime. Relatively prime numbers only have the number 1 as a common factor. 65 and 70 also have 5 as a common factor, so they are not relatively prime.
yes
Yes.
Yes. hcf(65, 112) = 1.
