How do I answer this?

Answer:
2k³ is the GCF.
Step-by-step explanation:
GCF of [tex]10k^{3} ,6k^{3}[/tex]
Finding the factors:
=10k³[Factoring 10k³]
=2×5×k×k×k
=6k³[Factoring 6k³]
=2×3×k×k×k
Common factors in 10k³ and 6k³.
=2×k³
=2k³
GcF
[tex]\\ \tt\hookrightarrow 2(k)(k)(k)[/tex]
[tex]\\ \tt\hookrightarrow 2k^3[/tex]
