look in /etc/passwd. The 4th field is the gid of the group.
Then look in /etc/group, to see what the name of that group is.

I don't know for your specific UNIX variaent, but on Solaris
# useradd -g groupname ....
will work. You can use either the groupname or the gid.

Please note my email address changes periodically to avoid spam.
It is always of the form: month-year@domain. Hitting reply will work
for a couple of months only. Later set it manually. The month is
always written in 3 letters (e.g. Jan, not January etc)

That only tells you what group is the primary group of the user, and NOT what
groups the user is in.

You want to look at the /etc/group file. Search for existing user's user name
and you will find all the groups it belongs to. You can then add your new user
to the same groups.
Optionally, you can use the 'groups' command to see which groups the 1st user
belongs to:
# groups user1
And then user useradd or usermod with the -G option. See 'man useradd' and 'man
usermod' for more info. Assuming, of course, that your platform supports
useradd/usermod.
