Well, isn't that just a happy little question! The greatest common factor of 4, 8, 15, and 20 is 1. You see, the numbers don't have any common factors other than 1 because they don't share any other numbers that can divide them evenly. Just like how every tree in our painting is unique and special in its own way!

Oh, dude, the greatest common factor of those numbers is 1. Like, it's the biggest number that can divide all of them without leaving a remainder. So, yeah, 1 is the winner here. Cool, right?
