Where 2324 fits
Why 2324 is special
It is the source of HTTP status code 418, 'I'm a teapot', which is the only joke in the status code registry to survive repeated attempts to remove it.
Not just a mathematical number
2324is also used in ways where ordinary arithmetic doesn't apply — each listed below with what genuinely does and doesn't follow from it.
- Mathematical number
A genuine quantity — its mathematical properties (prime, square, factors, and so on) are real facts about it.
A genuine quantity that ordinary arithmetic applies to — it can be prime, even, a perfect square, added to another number meaningfully, and so on.
- Code
Also used as a code — HTTP status codes.
An assigned identifier from a fixed registry or standard — its digits don't represent an amount, and arithmetic on it is meaningless (HTTP status 404 + 1 is not a 'better' status; it's a different, unrelated code).

In historical numeral systems
Egyptian
2 lotuses, 3 coils of rope, 2 hobbles, 4 strokes
2 × 1,000 + 3 × 100 + 2 × 10 + 4 × 1 = 2,324. The signs are simply repeated and added; where they sit on the line is a matter of layout, not value.
Babylonian
3 corner wedges + 8 vertical wedges (sixties place), 4 corner wedges + 4 vertical wedges (units place)
38 × 60 + 44 = 2324. Places are separated by a space on the tablet, with the higher place written first.
Systems that simply cannot reach this value are left out. Where a script needs a font most readers do not have, the reading is given instead of the glyphs — see number systems for each system in full.

418 entered the HTTP status code space through HTCPCP and remains reserved there.
HTCPCP defined status code 418, which outlasted the joke and repeated attempts to reclaim the number.
View 418 →Technology & computing
RFC 2324 was published on 1 April 1998 and defines HTCPCP, including the 418 response. Proposals to reclaim 418 for real use were rejected after public objection, and it remains reserved.

Common questions
Is 2324 a prime number?
No, 2324 is not prime.
What are the factors of 2324?
The factors of 2324 are 1, 2, 4, 7, 14, 28, 83, 166, 332, 581, 1162, 2324.
What is 2324 in Roman numerals?
2324 in Roman numerals is MMCCCXXIV. IV is subtractive: one before five — five minus one. Written additively it would be MMCCCXXIIII, which Roman inscriptions used freely — the strict subtractive form is a later convention.
