Composite numbers (Posted on 2003-03-05) Difficulty: 3 of 5
Find 2000 consecutive composite numbers.

(Of course you can't do this by trial and error alone)

For those who do not know what a composite number is, it is any integer greater than 1 that is not prime. (4, 6, 8, 9, ...)

well first, i thought of factorial numbers. for example, 4! is divisible by 1,2,3, and 4. therefore, all you have to do to find 2000 consecutive numbers that are compostie, you start with 2001!+2, then go until 2001!+2001 and you have your answer.
