If this is true how would I factor it? Would it still be the rule of the first row multiplying the first column etc?

Yes. In general you can multiply matrices so long as the dimensions conform. E.g.
(n x m) (m x n)
will result in an (n x n) matrix.
Perform the multiplication just as you would for square matrices: sum of the row vector times column vector.

Only if you're taking 1x2 columns vectors and dot producting
them with 2x1 rows.
Make sure what your multiplication order convention is
is it the columns of the right matrix on the rows of the left?

Yes. M X N multiplied by (N X M) = M X M
