13999.
It is: 1,000,000-1 = 999,999
1000000 is, itself, a whole number.
100000 - 1 = 99999
1 000 000 000 (One billion, U.S. and scientific. One thousand million, Britian. One milliard, other countries.)
4 000
The least whole number is 1590000 and the greatest number is 1999999
I think it is quadrillion = 1 000 000 000 000 000. "A" hundred does not count.
200 000 000
The next number would be one octodecillion and one, or 1 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 001 (U.S. and scientific. The British and other country version would be a one followed by 107 zeros, followed by a one.) If you meant, what series of numbers comes after octodecillions, it's novemdecillions.
