How do I find to which distribution (for example, RHEL or Centos or Suse) a RPM file belongs to?
I have a RHEL box, can I use RPM provided at link, https://dl.fedoraproject.org/pub/epel/6/x86_64/repoview/libRmath.html
Yes, you can determine the original package source for an RPM. The RPM header has a wealth of information about the package, including the Vendor and Packager.
To view the information on a package, use the rpm command as follows:
rpm -q -i -p libRmath-3.2.3-4.el6.x86_64.rpm
-q means to query the RPM file
-i prints out the information contained in the RPM header
-p Points RPM to the file to query. You can also pass it a URL if desired.
For the package you mentioned, here is the output of the above command:

Summary : Standalone math library from the R project
Description :
A standalone library of mathematical and statistical functions derived
from the R project. This package provides the shared libRmath library.
Whether or not the RPM is compatible with the system you are trying to install it on is a different issue. You can either do it by testing or stick with a distribution you know to have a similar set of libraries as your target system.
