Referencing theorems by numbers

Question

I was wondering if there was a way that I could reference the numbers of the theorems in my document would actually having to write "theorem 1.11". So that if the numbering of my theorems change then my referencing of them automatically does as well?

Thanks for any help

@IanThompson that is about referencing sections and my question is about referencing theorems/lemmas. I thought there might be a way to do what is in that link automatically for theorems. — hmmmm, Jun 07 '14 at 12:38
@IanThompson It would be good if you update your answer to cover also this case. — egreg, Jun 07 '14 at 12:53
@IanThompson I meant adding something that can cover also this problem. A newbie might not know that \label is allowed also after \begin{thm} and so on. — egreg, Jun 07 '14 at 13:02
also useful -- Understanding how references and labels work -- although that one doesn't mention theorems (or cleveref) either. — barbara beeton, Jun 07 '14 at 13:20

You can use the cleveref-package to solve your problem.

\documentclass[12pt]{article}
\usepackage[utf8]{inputenc}
\usepackage{hyperref}
\usepackage{cleveref}
\newtheorem{theorem}{Theorem}


\begin{document}
\begin{theorem}\label{Th_1}
This is my theorem
\end{theorem}

From \cref{Th_1} ...

\end{document}
