Google's Recrawl Frequency Varies from Daily to Monthly

Google recrawls URLs at different rates based on factors such as the frequency of updates on the webpage and the type of content. For instance, new stories are likely to be recrawled multiple times per day because they are often updated with corrections or additional information. In contrast, older stories might not be recrawled for several months if they are not expected to change frequently.

To expedite the removal of a page from Google's index, you can use the Google Search Console removal tool. This is especially useful if you've added a 404 status code to a page and don't want to wait for Google's next crawl, which could take several weeks to months. According to John Mueller, the verified removal tool is the fastest method, while the public removal tool takes a few days as it needs to verify the URL properly.

It might take Google several weeks to months to remove a page with a 404 status code because that is the rate at which Google may recrawl less frequently updated URLs. Google does not prioritize recrawling pages that are not expected to change often, such as older content. Therefore, if a page has been given a 404 status, it will not be immediately detected until the next scheduled recrawl by Google.
