dnf install yum-utils

Then you can run:

package-cleanup --leaves List leaf nodes in the local RPM database. Leaf nodes are RPMs that are not relied upon by any other RPM.

package-cleanup --orphan List installed packages which are not available from currently configured repositories.

Its not automatically safe to erase the packages you find.
