22 is not relatively prime
yes, they are relatively prime.
Yes, 62 and 121 are relatively prime
False. Consider 4 and 9. Neither are prime, but they have no common factors other than 1 and are therefore relatively prime. More generally, any two numbers p^n and q^n where p, q both prime and n<>p or q and n>1 are relatively prime. This is by no means all pairs of relatively prime numbers, but it's an easy way to find examples where neither of the pair is prime.
211 is a prime number, and is not a factor of 210, so yes, they are relatively prime.
Two numbers are relatively prime if their GCF is 1.
An easy way to find a number relatively prime to another number is to find a nearby prime number. For example, 53 is relatively prime with 50. The following pairs are relatively prime. 3, 50 19, 50 37, 50 49, 50 50, 69 50, 201 50, 341 Any number that is not divisible by 2 or 5 will be relatively prime to 50.
The GCF of two prime numbers is 1. 4, 9 and 25 are relatively prime.
No, they are not relatively prime.
It can be. 34 is relatively prime to 35. 34 is not relatively prime to 40.
25 is relatively prime with 36. 25 is not relatively prime with 35.
It can be. 26 is relatively prime to 27. 26 is not relatively prime to 34.
Their GCF is 9
