I am traveling by train from Gatwick to Chatham on 10th July and then on the 13th I am traveling from Chatham to Portsmouth. I am then going from Portsmouth to Gatwick on the 19th.
What is the cheapest train ticket and can I get it in one ticket?

I am no expert but as a matter of common sense it seems to me that you are making 3 quite separate journeys and so will require 3 separate single tickets. You may save a little money by booking in advance, rather than on the day:
You technically could have that as a combination of return tickets (there are ways to do it), but it's very complicated (other forums like RailForums have much more knowledgable people about ticketing if you really want to go that route)
I would just get them as 3 separate tickets as Elwyn mentioned

So this would be considered 3 journeys. The closest way to consolidate would be through something like Interrail, but I think it is safe to say that is overkill for this situation.

The UK train system is charitably described as "nebulous" and uncharitably as [unprintable]
You can penny pinch to a large degree, but all of those methods assume your time is worth £0.00
In general, you are usually better off using a service like The TrainLine as it builds fare splitting into it's ticket search
EDIT: See also trainsplit.com (Thanks @Rob)
I have searched your journeys and given a little costing for each in the form
Origin -> Destination [Ticket Provider]: £ Cheapest-listed-price
Bear in mind that services like the Trainline will add on a fee of around £1 - £2 for the convenience. However, it does mean you can manage tickets more easily, digitally
OR
Gatwick -> Chatham [Trainline]: £23.60

Looks like you would be best using a digital ticket system. The only journey you could maybe save on is the Portsmouth -> Gatwick
journey, but even then you'll only save £1.50 but at the cost of managing all the tickets. For the above I could find the cheapest by booking with the provider, but I could also easily find more expensive tickets than what was listed on the trainline.
