In my blog under Nadamadumnumbers I had mentioned about Number 123 being a Blackhole number.
Here is another example of a Blackhole number.
Take any whole number and write out it's numeral in English such as FIVE for the number 5.Count the number of characters in this spelling.In this case it is 4 or FOUR.So work now with 4 or FOUR.You will get 4 again.
Another Example 152.This appears as ONE HUNDRED FIFTY-TWO.Now count the characters.You may include spaces and hyphens in your count.The total count is 21.Repeat again with 21 i.e TWENTY ONE.This gives the count 10.viz TEN.Repeat again with TEN.You get 3 or THREE.Repeat again 5 or FIVE.Repeat again You will end up with 4..Similarly 163 will gradually give you 23,12,6,3,5 and finally 4.
Try with any other number.You will always end up with 4,the blackhole number.
Do you not find this interesting?
Though the result is language dependent,other languages may have a comparable property but not necessarily with 4 as the Blackhole.
