Answer:
2c^5 is the greatest common factor.
Explanation:
I believe you meant 50c^6 and 16c^5. c6 and c5 have no meaning. c^6 and c^5 are the sixth and fifth powers of c, respectively.
What do the two terms of 50c^6 and 16c^5 have in common? c^5 is common to both c^6 and c^5, and so, if we factor out c^5, we get:
c^5(50c + 16).
Note that 50c and 16 have only 2 as their common factor: 2(25c + 8). Thus, the final factored form of 50c^6 and 16c^5 is 2c^5(25c + 8).
2c^5 is the greatest common factor.
