The reason for making this topic was because I need a strait-forward, no guess method to solve GCF of an equation to factor something like (x^(2)-7x+6) because guess and check takes too long.
EDIT: I looked at some TI-83 instructions and was able to figure it out! Matrix>Catalog(Shift+4)>GCD(>and type "GCD([first term],[second term],[etc.])"
