Is there a way to find the monic least common denominator of a transfer matrix?

Greetings. Please consider the case in the image below:

Is there a way to program this into MATLAB? At least for this case so maybe I can figure it out for the general case. Please note that the long division in this example is not required, I will ask the user to input the numerators and denominators after performing long division.

The goal is to get a common denominator and a numerator matrix.

Thank you in advance.
