Hello,

Is there a function in R with which we could find the greatest common
divisor directly?


Learn to search:

> rhelpSearch <- function(string,
restrict = c("Rhelp10", "Rhelp08", "Rhelp02", "functions" ),
                  matchesPerPage = 100, ...)
RSiteSearch(string=string, restrict = restrict, matchesPerPage = matchesPerPage, ...)

> rhelpSearch("greatest common divisor")

A search query has been submitted to http://search.r-project.org
The results page should open in your browser shortly


Or use package "sos"

Or is there a funciton, which could help us to find the remainder of a
division directly?

Same advice ... with the additional search strategy of:

?"%%"

#integer division remainder, but read all the caveats about using R for activities regarding the different data types of numeric and integer.


Best wishes! Thank you!
