Answer:
None of these options are the GFC.
If you meant 72, then the greatest common factor would be 12.
Explanation:
None of these options can be divided with 727.
727 รท (any of these numbers) is not a solid number.
If you meant 72, then the greatest common factor is 12, because it is the highest number that can be divided evenly with the three options.
I hope this helps :)
