If a Data Record is currently selected in the "Data" tab, this line will list the name you gave to that data record. If no data record is selected, or you have no entries stored for this calculator, the line will display "None".

Greatest common factor:

This is the greatest common factor for the numerator and denominator you entered. If the result is one, it means that your entries do not have any factors in common other than one -- meaning no reduction or simplification is possible. But in either case, the fraction reducer calculator will still report its conclusions and show its work below this line. Plus, if the fraction is an improper fraction it will convert it into a mixed number.
