5: Five is a pretty nice number, none of the numbers in the ones are that bad. It’s also prime which is something I always find pretty, and even though it’s a multiple of 5 it’s not that bad.
15: Not the greatest number, it’s not prime, and a multiple of 5… but at least it’s a multiple of 3 which saves it a bit.
1: 1 is great. On a scale of 0 to 10 it’s a solid 8. It’s my 3rd favourite number in between 0 and 10. It’s cool because you can multiply anything by 1 and get the same thing, and all prime numbers are divisible by 1, and so much more.
6: six is fine, it has a certain ambience to it no other number has. Just the way it looks, and it’s a perfect number as well.
21: This one is funny. I’ve heard at least one person call it a prime number and to be honest a child 5 years old could probably confuse it. But I like it because it’s a multiple of 7 and 3. Quite a nice number.
107: I don’t know much about this but it’s prime so it’s got a nice quality.
47176870: BB(5). Pretty cool.
Maybe I should’ve included 38 (BB(2, 3)) and 3932964 (BB(2, 4)) as well
