How do you remove an isolated number from a string in R?

This is a silly question, but I can't seem to find a solution in R online. I am trying to remove an isolated number from a long string. For example, I would like to remove the number 27198 from the sentence below. 

x <- "hello3 my name 27198 is 5joey"

I tried the following: 

gsub("[0-9]","",x)

Which results in: 

"hello my name  is joey"

But I want: 

"hello3 my name is 5joey"

This seems really simple, but I am not well versed with regular expressions. Thanks for your help!

We can specify word boundary (\\b) at the end of one or more digits ([0-9]+)

gsub("\\b[0-9]+\\b", "", x)
#[1] "hello3 my name  is 5joey"
