{{{-66a^4}}},{{{11a^5}}}


Step 1.  First look at the numbers.  The greatest common factor for the numbers (or coefficients) is 11.


Step 2.  Then look at the a-terms and find the greatest exponent common between the two terms.  In this case, it's {{{a^4}}}


Step 3.  ANSWER:  The greatest common factor is {{{11a^4}}}.


I hope the above steps were helpful.
