#### Primes

Care for a little recreational computing? Know how to compile (javac Primes.java) and run (java Primes) Java? Here’s a little tool that finds and shows the prime factors of a number. A few “interesting” numbers:

- 9223372036854775807 - the largest number the program can handle (2^63-1)
- 2286236833561957 - a number with prime factors greater than the one millionth prime (you can specify the size of the table of primes that the program uses)
- 614889782588491410 - try it
