Finding factors is kind of a guessing game, if you have choices to pick from you can divide the number by the possible factor and if it turns out to be a whole number then that possible factor is a factor. let me show you
46/3=15.3 so three is not the answer 46/2=23 so, 2 is a factor
the possible answers you have look weird, i am not sure what 7B.3, 13c.2, or 23D.3 means but I hope I helped
