I could write out the lengthy process, but I think it's easier to just use an existing program - there are plenty of good ones...
One I've liked is "GCF and LCM Finder" (http://www.ticalc.org/archives/files/fileinfo/167/16720.html ). "GCF and LCM of 2 or more numbers" (http://www.ticalc.org/archives/files/fileinfo/283/28373.html ) is also pretty good...
In case you've never downloaded before, here's what you do:
1. First, use a transfer software. The standard one is TI Connect. If you don't have the installation CD that came with your calculator, go to the official TI EDUCATION download site at http://education.ti.com/educationportal/appsdelivery/download/download_interim.jsp?applicationId=183&contentPaneId=7 . Choose a language, download, then install.
2. Get a USB cable for the actual download. One came with the calculator, but if you don't have it, they are easy to get and very versatile.
Hope I've helped! =)

The Algo is
Sort the given numbers in ascending or descending order
For i = 1 to n-1
find the gcf of the first two numbers
Take the gcf and set i = 3, find gcf of gcf and this number and continue till the end.
The final gcf is the answer
For LCM
Multiply all the numbers
Divide by the GCF
