Oh, dude, let me break it down for you. So, if three numbers are relatively prime, it just means they don't have any common factors other than 1. In this case, 8, 12, and 15, well, they do have a common factor of 1, but they also have other common factors like 2 and 4. So, nope, they're not relatively prime. Like, it's cool, no big deal.

CoachTo determine if 8, 12, and 15 are relatively prime, we need to find the greatest common divisor (GCD) of the three numbers. The factors of 8 are 1, 2, 4, and 8. The factors of 12 are 1, 2, 3, 4, 6, and 12. The factors of 15 are 1, 3, 5, and 15. The only common factor among 8, 12, and 15 is 1, making them relatively prime.

Are 48 and 49 relatively prime numbers?
Numbers are relatively prime if the only factor they have in common is 1. The factors of 48 are 1, 2, 3, 4, 6, 8, 12, 16, 24, and 48. The factors of 49 are 1, 7, and 49. The only common factor is 1. Therefore, 48 and 49 are relatively prime. Also, any two numbers whose difference is 1 are always relatively prime.
What is relatively prime?
Relatively Prime numbers are sets of two or more numbers having 1 as their greatest common factor (gcf). All even numbers have 2 as a common factor, so no even number is relatively prime with any other even number.
What is the greatest common factor of 8 and 11?
The GCF of 8 and 11 is 1. The factors of 8 are 1, 2, 4, and 8. The factors of 11, which is a prime number, are 1 and 11. The only common factor is 1, so it is the greatest common factor, which means the 8 and 11 are relatively prime. You can also determine this by looking at the prime factors. The prime factors of 8 are 2, 2, and 2. The prime factors of 11 are 11. There are no prime factors in common, so the numbers are relatively prime, which means their only common factor is 1.
How many numbers between 20-30 are relatively prime to 25?
If you don't include 20, 25 and 30, all of the numbers in that range are relatively prime to 25.
What is the GCF of 15 and 8?
The prime factors of 8 are 2, 2 and 2 The prime factors of 15 are 3 and 5 The6y have no common factors - other than 1.
