Using parameter substitution on any POSIX shell:
Code:
str='<a class="model-link tl-tr" href="lastSuccessfulBuild/">Last successful build (#1753), 40 min ago</a>'
str="${str##*(#}"
echo "${str%%)*}"

Using awk program:
Code:
echo "<a class="model-link tl-tr" href="lastSuccessfulBuild/">Last successful build (#1753), 40 min ago</a>" | awk '{gsub(/.*\(#|\).*/,x)}1'

Using sed
Code:
sed 's/.*(#\([0-9]*\)).*/\1/g' input_file

I guess the input file do contain more than this single line. Here is how I would do it.

Code:
awk -F"#|)" '/lastSuccessfulBuild/ {print $2}' infile
1753
