Formulas to see if names in one column exists on the names in the second column

Hey everyone,

I am at work and I need some help!
I have two columns listing about 400 and 500 names respectively.
First Column has names in alphabetical order and the second column is random.
One column has names in this format: Last name, First name
and the other column lists the names as first name and then last name without the comma
I am trying to see if the list of names in one column exists in the other.

Is there a way to see this without changing the format of the names in each column? If so do I have to erase the comma?

Thanks in advance !
