How To UnInstall No Maching Client from CentOs

[dxgamers]

Hello,
I need to uninstall NX Client which i insatlled few days ago.
I tried this command.

rpm -e nxclient

But it shows this error:

error: Failed dependencies:
        nxclient >= 3.0.0 is needed by (installed) nxnode-3.4.0-13.i386
        nxclient >= 3.0.0 is needed by (installed) nxserver-3.4.0-12.i386

I think this Nx Client is taking too much ram of my server.
Therefore, i need to uninstall it.
Hoping for a Quick Reply.
