Yes, 45 and 64 are relatively prime because they do not share any prime factors.
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.
92 = 22 x 23 115 = 5 x 23 Then there GCD is 23 and 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."
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.
No, they are not relatively prime.
No two even numbers are relatively prime. The GCF is 2.
2 is the greatest common factor and it is prime
Yes, 45 and 64 are relatively prime because they do not share any prime factors.
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.
45 and 64 are not prime numbers because they both have more than two factors
Their GCF is 1.
No, they are not.
Their GCF is 1.
yes
Yes, they are.
No because their greatest common factor ( gcf ) is greater than one their gcf is 11 therefore 11 and 22 are not relatively prime
