In accordance with a sensible procedure practiced by User:GUllman, the articles for the numbers 401 to 499 will be 'grown' here in the article on 400 until they are big enough to merit their own articles. Once that happens, a new page is created for the number in question, linking back to this page, and this page is changed to indicate that the number now has its own article. User:PrimeFan

400th anniversary[edit]

How do you name a 400th anniversary, quadricentennial or quatercentenary?? "Centennial" and "Bicentennial" have the same suffix, so using extrapolation, "quadricentennial" should make more sense?? Any opinions?? 66.245.124.50 01:56, 7 Nov 2004 (UTC)

Quadricentennial sounds more correct to me. PrimeFan 18:08, 15 October 2005 (UTC)

Eventually yields 495[edit]

I tried the 495 digit thing with a number I randomly typed, 194. Got to 495 after about seven steps. Haven't checked for any other three-digit integers. PrimeFan 18:08, 15 October 2005 (UTC)

Introduction[edit]

Currently, the introduction reads thus: 400 (four hundred) is the natural number following three hundred [and] ninety-nine and preceding four hundred [and] one. Why does the introduction say "three hundred [and] ninety-nine" as well as "four hundred [and] one"? The word and is not used in numbers unless expressing fractions. --דניאל - Dantheman531 00:01, 7 September 2006 (UTC)

In reply to the above, I at least am pretty sure that "four hundred and one" is in common English usage (both British and American). To say it's "not used" is simply not true. 62.244.190.66 (talk) 12:02, 23 January 2008 (UTC)

It's common language, but it's improper. — Preceding unsigned comment added by PixelScientist (talkcontribs) 16:48, 4 September 2011 (UTC)
In standard British English it is always used: "Four hundred one" sounds very odd. The classic game of darts ends with the cry of "One hundred and eighty" when the final score is reached. Always. 85.211.13.188 (talk) 12:07, 19 October 2011 (UTC)

425[edit]

Is there any greater meaning to the number 425? I've seen hats with the number on them. --Brandon Dilbeck 23:16, 27 February 2007 (UTC)

427[edit]

The sum of the factors of 427 (1, 7, 61, and 427) equals 496, which is a perfect number, but there are 4 factors, which is not a perfect number, so 427 is not a sublime number. —Preceding unsigned comment added by 208.73.31.50 (talk) 20:23, 26 July 2008 (UTC)
