Is 70 and 195 relatively prime?
No, they are not relatively prime.
Is 70 and 79 a relatively prime?
Yes, they ARE.
Are 21 and 66 relatively prime?
No, they are not. They share 3 as a factor.
What makes two or more numbers relatively prime?
Two numbers are relatively prime if the only factor they have in common is 1. Example: 12 and 17 are relatively prime because they have only 1 as a common factor. 12 and 21 are not relatively prime because they have 1 and 3 as common factors.
What is the greatest common factor of 21 and 44?
The GCF of 21 and 44 is 1. The only proper divisors of 21 are 3 and 7. The only proper divisors of 44 are 2,4 and 11. So, could it be that there are no common factors? No! We forgot about 1 which is a divisor of every number. 1 is the only common factor of 21 and 44, so it has to be the greatest. Rule: if nothing else divides two numbers the greatest common factor is 1. We say such numbers are relatively prime to each other. 21 is relatively prime to 44 and 44 is relatively prime to 21 but neither number is prime. Exercise : Prove : If p and q are two different primes, then p and q are relatively prime.
Is 21 relatively prime?
It can be. 21 is relatively prime with 32.
Is 70 and 195 relatively prime?

Why is 17 relatively prime with 21?
Yes, they are relatively prime.
Are 21 and 44 relatively prime?
Yes, they are relatively prime.
Are 16 and 21 relatively prime?
Yes, they are relatively prime.
Is 4 and 21 relatively prime?
Yes, they are relatively prime.
Are 14 and 21 relatively prime?
