Answer:
2c
Step-by-step explanation:
The greatest common factor is the largest integer factor two numbers have in common. A faster way to find it is to prime factorize the number, but in this case, it is easier to just list out the factors;
30c = 2 * 15 * c
8[tex]c^{6}[/tex] = 2 * 4 * c * [tex]c^5[/tex]
Greatest common factor;
2 c
