Their GCF is 1.
Yes, 45 and 64 are relatively prime because they do not share any prime factors.
45 and 64 are not prime numbers because they both have more than two factors
Their GCF is 1.
22 is not relatively prime
No, they are not relatively prime.
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."
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.
Since the GCF of 45 and 56 is 1, they are 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.
No, they are not.
No, they are not.
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.
