Yes.
Relatively prime numbers share no common factors other than 1.
There are several ways to achieve this. For example, any two prime numbers. Or just multiply different small prime factors for each of the numbers - picking different prime factors for each - for example, a power of 2, and a power of 3.
No. They are both composite numbers. They are not relatively prime either.
Relatively prime or co-prime.
No.
Two composite numbers may or may not be relatively prime, depending on their factors. Relatively prime numbers are sets of two or more numbers having 1 as their greatest common factor (gcf). All even numbers have 2 as a common factor, so no even number is relatively prime with any other even number.
Not necessarily. 4 and 9 are relatively prime and both are composite.
No it does not mean that.
No, they need not be.
both are composite numbers
37 is prime, the other is composite.
