Using cut you can only select fields from the left to the right. If you don't know how many fields you will have after the cut then you will not be able to get the last field.
But there is a solution for this using rev. Reverse the string, cut and get the first field and reverse it back. So in your example "abcd/efgh/ijklm/nopq":

echo "abcd/efgh/ijklm/nopq" | rev | cut -d/ -f1 | rev

the result will be "nopq"
