Help with math expression. (Factoring or something)

The original expression:
6m^6n + 7m^5n^2 + 2m^4n^3

I got to
(m^4n)(6m^2 + 7mn + 2n^3), but this is where I got stuck.

Thanks in advance, my fellow Bananas. <3

6m^2 + 7mn + 2n^2 not 3.

6m^2 + 7mn + 2n^2 = (2m + n)(3m + 2n) so,

6m^6n + 7m^5n^2 + 2m^4n^3
= (m^4n)(2m + n)(3m + 2n)
