awk/sed/ksh script to cleanup /etc/group file

Many of my servers' /etc/group file have many userid's that does not exist in /etc/passwd file and they need to be deleted.
This happened due to manual manipulation of /etc/passwd files.
I need to do this for 40 servers.
Can anyone help me in achieving this? Even reducing a step or two will be greatly appreciated.
Thanks in advance.
