561 is a natural number that succeeds 560 and comes before 562.

Properties
561 is an interesting number primarily for the reason that $$561^2-561^1-561^0=314,159$$. The resulting number 314159 contains the first 6|six decimal digits of pi.

561 has 3, 11, and 17 as it's prime factors, incidentally the sum of those prime factors is 31, which happens to be the first 2|two decimal digits of pi.

It is also the first.

Origin
561 was noted for having this property by Edwin Shade about two years ago.

Note
The person who made this put in too many links, so I gave him something else to pick on. [Link has been redacted due to containing viruses.] [[Special:Contributions/64.203.44.137|64.203.44.137]] 22:35, November 13, 2017 (UTC)Adrian

Edit from me: It's a wiki page, just ruin it.
