22 is not relatively prime
Yes, 45 and 64 are relatively prime because they do not share any prime factors.
Numbers are either prime or they aren't. In this case, 45 is divisible by 3 and 15; sixty-four goes into 2, 4, 8 and 32. The term "relatively prime" compares two numbers and their common factors. If the GCF of the two numbers is 1, then they are "relatively prime."
The LCM is 5184. The numbers 81 and 64 have no common factors. When you have two relatively prime numbers, you find their LCM by multiplying them. So 5184 is 81x64.
yes, they are relatively prime.
No, they are not relatively prime.
No, they are not relatively prime.

No.
22 is not relatively prime
No, they are not relatively prime.
No, 144 and 165 are not relatively prime. For them to be relatively prime, the number 1 could be their only common factor, but they also have 3 as a common factor.
Yes, 45 and 64 are relatively prime because they do not share any prime factors.
No, two even numbers cannot be relatively prime.
Yes.
No.
No two even numbers are relatively prime. The GCF is 2.
