To find the Greatest Common Factor of 207c³ and 108c², first factor them down to their primes and see what they have in common.

207c³ 108c²

∧ ∧ ∧ ∧

9·23 c·c·c 9·12 c·c

Option D is the correct option.

Solution,

 $- 4 {x}^{2} (12 {x}^{4} - 4 {x}^{3} + 5) \\ = - 4 {x}^{2} \times 12 {x}^{4} + 4 {x}^{2} \times 4 {x}^{3} - 4 {x}^{2} \times 5 \\ = - 48 {x}^{6} + 16 {x}^{5} - 20 {x}^{2}$ 

hope this helps...
