    Greatest common factor



    I think the greatest common factor is the one I mark in the image, but wolfram gives me so many different answers I'm not sure if I am correct. My confidence is always shaken when wolfram gives me multiple results which may be all totally equivalent but which one is factored the most out of those?

    The greatest common factor is the stuff outside the brackets in the answer you chose, and the answer you chose is the fully factorised form of your expression.

    Thanks for clearing that up, so the others are not completely factored? Or they are equally completely factored to the one I chose?

    The other ones are not completely factored. You can check this yourself, can you see any other common factors inside the brackets that can be taken out?
