42 = 2 x 3 x 7 120 = 2^3 x 3 x 5 48 = 2^3 x 3 63 = 3^2 x 7 I guess the feedback to the first person will be, you type really fast and know how to do something that I don't. I would suggest asking for the *method* to solve these problems rather than just the *answers* otherwise you will never learn how to do them yourself. Factorization can be done several ways. If you'd like me to explain the methods I will, but if you want to give best answer to the fastest person with just the answers, then by all means, go ahead.
