Emma says the gcf of 16 and 12 is 48. her friend grace says the answer is right. who is right? explain me plz

the mistake in the pattern is that :

b. the decimal point was moved one too many place values each time

the correct pattern could be made by :

b. moving the decimal point to the right the same numbers of place values as the exponents

1. minimum

2. 6400

3. eight

hope this !
