@rsmth this is how this could work. You define a minimum length of the number you want to extract and then use this regex to split the text into several (full) numbers. If you want to take care of decimals the regex might have to be different
(?s).*?\b(\d{2,})\b(?:.*?\b(\d{2,})\b)?(?:.*?\b(\d{2,})\b)?
