How to put a line number every line of algorithmic

I am looking for a way to have a number for every line in algorithmic:

documentclass{article}
usepackage{algorithm} 
usepackage{algorithmic}
begin{document}
    begin{algorithm}
        caption{Some alg}
        begin{algorithmic}
            REQUIRE a,b, c
            STATE d = a + b + c
            STATE d = d/2
            STATE d = d/3
            RETURN d
        end{algorithmic}
    end{algorithm}
end{document}

I would like to have:

 Require: a,b,c
1 d = a + b + c
2 d = a + b + c
3 d = d/2
4 d = d/3
  return d
