Factoring Calculations
Hi,
I have my maths test on next week and also i have little struggle on factoring calculations. Basically i have used factoring calculator to solve my homework problems. For class tests, i don't have this type of options. So, can anyone help me how to do factoring easily without calculator? any shortcuts? I am horrible at math expression factoring. thanks in advance.

divide by all prime below the square root of it.

I have never seen a math exam in which factoring numbers were given as problems. Noone factors numbers without a calculator except the trivial 23 digits ones that arise in the context of other problems. There is no such thing as "math expression factoring". It is gibberish.

Perhaps harishdeen is referring to factoring polynomials?

Nope. That factoring calculator factors numbers.
Perhaps if the OP had worked on doing his/her homework by hand instead of using the tools available on the internet, then he/she wouldn't have this problem.

I understand, Bob, that most (if not all) of your experience has been in higher education, but I guarantee that if you have children or if you have taught mathematics to children, it is most certainly not true that you "have never seen a math exam in which factoring numbers were given as problems". Or, if not such an exam, then certainly at least a quiz. It is therefore quite unfair to dismiss the OP's question as trolling.

Note that integer factorization is useful for factoring polynomials  try factoring 132x^{2}  83x  1365 by hand if you disagree. Paul

I think I have figured this one out: the OP is at least spamming and at worst a bot. Note that the unusual phrase "expression factoring" appears in both the OP's post and in the URL for the "factoring calculator". Trying to drop keywords to bring Google searches their way, I'd guess.
