No.
For example: 9 and 27 are both odd but not relatively prime (they both have the factor 3).
All odd numbers that can not be divided by 3 evenly would be relatively prime with 18.
Any odd prime number.
Any odd number.
Yes, e.g. 3 and 5 are relatively prime, 27 (33) and 25 (52) are relatively prime...
They are all odd, and they are all prime numbers
All of the prime numbers are odd except for two.
There is an infinite amount of prime numbers all of which are odd numbers
All prime numbers are not odd. 2 is a prime, 2 is not odd.
Except for 2 all other prime numbers are odd. Otherwise, they would be divisible by 2 (and thus not a prime number). This does NOT mean that all odd numbers are prime, but that all prime numbers (aside from 2) are odd.
All prime numbers are odd, exept of the first prime number 2.
All prime numbers are odd except for the number 2.
Yes. Apart from 2, all prime numbers are odd.
