yes
Yes, they are. 5 is the only prime factor of 25 and 5 is not a factor of 18, so they have no prime factors in common, which is what relatively prime means.
Yes, e.g. 3 and 5 are relatively prime, 27 (33) and 25 (52) are relatively prime...
If you don't include 20, 25 and 30, all of the numbers in that range are relatively prime to 25.
No. Both are divisible by 5.
No, 50 and 65 are not relatively prime.
No, they are not relatively prime.
25 is relatively prime with 36. 25 is not relatively prime with 35.
No.
Yes, they are relatively prime.
Yes, they are relatively prime.
yes
Yes.
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.
It can be. 16 is relatively prime with 25.
The GCF of 26 and 65 is 13. 13 is a prime number. "Relatively prime" refers to numbers whose GCF is 1.
Yes. hcf(65, 112) = 1.
