ruby - Retrieve number from the string pattern using regular expression

I have a string "Search result:16143 Results found", and I need to retrieve 16143 out of it.

I am coding in ruby and I know this would be clean to get it using RegEx (as oppose to splitting string based on delimiters)

How would I retrieve the number from this string in ruby?
