Regex to remove string after last number?

There are a lot of regex out there but I couldn't find the solution to my specific problem.

Consider these strings:

my street 13a
mystreet 3 B
my street karlos 15A

How can I return those:

my street 13
mystreet 3
my street karlos 15

\d+[a-z,A-Z] matches the case "13A, 13a" and \d+ [a-z,A-Z] matches it with whitespaces. After this I would just use this:

myCutStr = myOriginalString.match(/\d+[a-z,A-Z]/g);
myNewStr = myCutStr.replace(/[^\d]/g, '');
myOriginalString.replace(myCutStr, myNewStr);

But can I somehow combine \d+[a-z,A-Z] and ignore white spaces in that regEx? So that this one \d+[a-z,A-Z] will match all of my kind even with whitespaces?

A single replace would be enough. That is, replace all the non-digit characters present at the last with an empty string.

string.replace(/\D+$/g, '');

OR

string.replace(/(\d)\D+$/g, '$1');
