Is 8 12 and 15 relatively prime?

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.
