The general gist of the question:
Peter has to go to an office store, an electronics store, a clothing store, and a sporting store. There are 4 office stores, 4 electronic stores, 8 clothing stores and 5 sporting stores. How many combinations are there?
Do I need to do a factorial? Or just multiply the numbers?
Thanks!!!

just multiply the numbers

I don't think you just multiply the numbers for this one. If the question said that he was going to all 4 office stores, all 4 electronic stores, all 8 clothing stores, and all 5 sporting goods stores and asked how many ways can he do that, then you would multiply them all together. That is not what the question is asking however.
