600 (six hundred) is the natural number following 599 and preceding 601.

Mathematical properties

Six hundred is a composite number, an abundant number, a pronic number and a Harshad number.

In other fields

In the United States, a credit score of 600 or below is considered a poor score, thus limiting available credit (or requiring the borrower to pay higher interest rates).
600 is also the advertised number of miles that NASCAR runs in the Coca-Cola 600, the longest race on any of the NASCAR circuits.
