You cant factor on the ti-84. however the ti-89 does do this but its almost easier to just do it in your head. Plus on the ti-89 the way you enter it in there is a very high risk for error.

96 plus 48 plus 84 is equal to 228.

26 plus 16 plus 84 is equal to 126.

48 and 84's highest common factor is 12.
