Git LFS - How to remove older versions of files from a git repository?

Question

I have a Git repository with several huge files. I am using Git LFS for large file support.

Today I received an email saying

Git LFS has been disabled on your personal account.... 

Current usage as of 19 May 2019 06:12AM UTC:

Bandwidth: 0.0 GB / 1 GB (0%)
Storage: 6.16 GB / 1 GB (616%)

The repository certainly does not have files of 6.26GB. However, possibly Git is adding up storage due to the older versions of file.

Can you help me how do I remove the previous version of files, only keeping the latest?

My problem is related, but not exactly the same.

I'm using JFrog Artifactory for Git LFS. We have plentiful storage, so storing past versions is not a problem on our "origin".

The problem is with the clone on my PC. I don't need all past versions there - but they pile up every time I push or pull. This takes up space in the .git\lfs\objects folder in the clone - and indeed filled up my drive!

As Aaron Voelkner pointed out in the answer, I can run git-lfs prune and it drastically reduces the amount of data stored locally.

$ git-lfs prune
prune: 2914 local object(s), 975 retained, done.
prune: Deleting objects: 100% (1939/1939), done.

If I wanted to look at older versions, I can still get them via origin, but this makes my local working much simpler.
