how to tell which repository and installed rpm came from?

[ron7000]

running centos (or rhel) 7.6, I have the base Centos (or RHEL) repositories installed, along with EPEL and ELREPO and NUX.
I use the gnome software gui and search on some software, FreeMat or MP3/H264 codecs for example, and install them.
In the future, I can do an rpm -qa and get a list of all rpm's installed.

Is there a way for a given installed rpm, to find out which defined repositories under /etc/yum.repos.d/ it came from?

And also once registered and doing the RHEL optional rpm activation described on the Fedora EPEL website my redhat.repo file is some 4000+ lines. The main ones that are enabled are
[rhel-7-server-extras-rpms]
[rhel-7-server-optional-rpms]
[rhel-ha-for-rhel-7-server-rpms]
[rhel-7-server-rpms]
... and so on.

Is there a way to tell which of those (assuming those are separate "repositories" ?) an rpm came from?

Like yum list gnome-software for example? If it's installed then it will be listed with e.g. @base at the end of the line when you yum list it.

@anaconda means that it was installed when you first installed the system.
