The general form from the old Unix days is:

  find . -type d -print | xargs chmod <permissions>

for all directories in the current tree, and:

  find . -type f -print | xargs chmod <permissions>

for all normal files in the current tree.  Using such a form guarantees
portability across all flavors of Unix and Linux.  <permissions> above are
either octal bitmaps (e.g., 770) or mnemonics, e.g. "ug+rwx,g-t,o=r".

That's going to depend on the permissions of the parent directory, not the
file itself.  They have to have write permission 'w', and if the file belongs
to someone else must not have the sticky bit set for group 't'.
