Yes, three and eight are prime to each other, meaning they are coprime. This is because their greatest common divisor (GCD) is 1; they do not share any positive integer factors other than 1. Since 3 is a prime number and 8 is a composite number, they have no common factors.
There are only 2, and these are 1 and 2.
The first three multiples of 9 are 9, 18 and 27. For them to be common, they need to be compared to another set of factors.
Eight factors.
