Factors of 44100 are 2 2 3 3 5 5 7 7
Just enter the integer to be factored in the box above and click "Go!". The factorization appears above, just below the box, as well as below these instructions in the Previous Outputs section. The output is deliberately simple. For instance, the factorization of 72 is reported as "2 2 2 3 3" rather than "23 × 32". This is a simple program and you're welcome to take it and adapt it. Adding multiplication signs of your choice to the output is a very simple matter. Making the program format exponents takes a little more work but is also simple.
Large numbers with a large smallest prime factor can show quite explicitly the shortcomings of factoring by trial division. On Mac OS 9, the cursor might change to the spinning disc for several seconds, and if you have music playing, it might pause while the calculation is going on. On Windows XP, Internet Explorer might show a dialog box informing you that a script on this webpage is making your computer sluggish, and offering you a chance to abort the script. I wrote this program to display a little message that says "Calculating..." while it runs, but I have never seen that message come up. If you need to factor a really large number, then I suggest you launch Mathematica or some heavy duty math program like that.
