How to exclude number followed by text?

Question

Regular Expressions

There is a text in which I am trying to find numbers.
There are no problems with this \d+:
But, if there is text after the number, we discard these numbers: \d+(?!\D).
Now these numbers are discarded, but at the same time, when finding other numbers, an error occurs (we get an incomplete number).

Example

Tell me where I make a mistake?

Answer 1

\d+(?![A-Za-z])
