What does error 404 mean
404 error is a situation when a communication between client and the server has happened but server could not locate the exact resource client was asking for may the resource itself was not available or for any other reason..
wiki pedia says : “The HTTP 404, 404 Not Found, and 404 error message is a Hypertext Transfer Protocol (HTTP) standard response code, in computer network communications, to indicate that the client was able to communicate with a given server, but the server could not find what was requested” source: https://en.wikipedia.org/wiki/HTTP_404
Now, let’s talk about :
When 404 error happens
First of all, let me make you clear that it’s the error from your end not from the hosting or the server end …
and following are the reasons to happen those crawl errors (404 error)

#2 coz,the resource page was initially available but now you have deleted that page, this also causes http status 404 – not found error.
#3 May be the content is still available but you have changed the url of that content , this also cause to get error 404 page…
Now:

finding 404 errors on your site is not that difficult google itself gives you that either you have those crawl errors in your site or not.
To find them you need to go to your search console or google webmaster tool ( whatever you say it )
This is my dashboard.
Now, let me go to the crawl section from the dashboard and then click on the crawl errors to check site for 404 errors if any errors are there or not ..
After you are in your webmaster tools dashboard, click on crawl>> crawl errors>>goto url errors>> as shown in above figure..

So, After you look at that you can know what is the cause of that error
if its simple misplaced words in url go to that url source in your website and fix it manually .. and if there is no chance to fix it manually as coz you might have deleted that page or you might have changed the url then you need to make use of 301 redirection
it means let’s say that i have one error, 404 error now , coz of that error whatever the backlinks that page had i will be loosing all the backlinks
also :
if i redirect i won’t lose any visitors coming to that page coz of the simple error .. so if I need to redirect this page to something relevant page ;
if not I can redirect it to the home page.
now let me show you this using one plugin in wordpress which helps to remove google 404 error within fraction of second
