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."

Are 45 and 64 relatively prime?
Yes, 45 and 64 are relatively prime because they do not share any prime factors.
Are 22 and 64 relatively prime?
22 is not relatively prime
Are 64 and 144 relatively prime?
No, 64 and 144 are not relatively prime. To be relatively prime, the only common factor they could have would be 1. They have other common factors such as 2, 4, 8 and 16.
Are 45 and 64 relativley prime?
Yes. 45: 3 x 3 x 5 64: 2 x 2 x 2 x 2 x 2 x 2 Because there are no common factors, the two numbers are said to be relatively prime.
What is the LCM of 81 and 64?
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.
Are 45 and 64 relatively prime?
Yes, 45 and 64 are relatively prime because they do not share any prime factors.
Why are 45 and 64 to be relatively prime?
Their GCF is 1.
Are 25 and 45 and 64 relatively prime?
Yes, they are.
Are 45 and 64 relatively prime why?
45 and 64 are not prime numbers because they both have more than two factors
What is the reason for 45 and 64 to be relatively prime?
Their GCF is 1.
Are 45 and 84 relatively prime?
No, 45 and 84 are not relatively prime.
Are 22 and 64 relatively prime?
22 is not relatively prime
Are the numbers 22 and 64 relatively prime?
No, they are not relatively prime.
Are 26 and 64 relatively prime?
A single number, such as 2664, cannot be relatively prime.
Are 39 and 45 relatively prime?
39 and 45 are not relatively prime because they have 3 as a common factor. Relatively prime numbers have no common factor greater than 1.
What is the greatest common factor of 45 and 56 and are they relatively prime?
Since the GCF of 45 and 56 is 1, they are relatively prime.
Are 18 and 45 relatively prime?
No, they are not.
