hi awholenumber

I don't know a good book for this but why not check out the Maths Is Fun teaching pages.  If you start at

http://www.mathsisfun.com/prime-factorization.html

you'll get a long way with what you want and there are many cross-links between pages so you can easily find other pages to give you more.  Or use the search with 'factors' or something similar.

I strongly recommend these pages because (1) they're free! and (2) the explanations are really clear.  Sometimes there are really helpful animations with interactive features and every page ends with some test yourself questions.
