Question

Find the greatest common factor of 8a 3 b 2 and 12ab 4.

Answer 1

Do you mean 8a³b² and 12ab^4?

If it is like this..
The GCF is 4ab²

Answer 2

4ab²

Explanation:

The two expressions are given as 8a³b² and 12ab⁴

Now factors of 8a³b² = 2 × 2 × 2 × a × a × a × b × b

and factors of 12ab⁴ = 2 × 2 × 3 × a × b × b × b × b

Now greatest common factor will be 2 × 2 × a × b × b

= 4ab²
