Math Paper - XKCD

Some numbers really like other numbers. Like 220 and 284, which are amicable (or friendly) numbers, so called because the sum of the factors of 220 is equal to 284, and the sum of the factors of 284 is equal to 220. That is,

1 + 2 + 4 + 5 + 10 + 11 + 20 + 22 + 44 + 55 + 110 = 284

and

1 + 2 + 4 + 71 + 142 = 220.

On the other hand, other numbers despise one another, eying them suspiciously at the grocery store, frequenting different restaurants to avoid awkward conversations, and cutting them off on the freeway. The reasons for this disdain varies widely…

Why doesn’t 3 like to hang out with 4?
Because he’s a square.

Why doesn’t 4 like 5?
Because he’s odd.

Why is 5 annoyed by 6?
Because she thinks she’s perfect.

Why is 6 afraid of 7?
Because 7 8 9.

Why does e dislike pi?
He’s more of a cake person.

Why doesn’t 144 like 288?
Because he’s two gross.
