Formatting does not change the value in a cell, merely how it looks.
However, you can achieve what you are trying to do by entering -1 into
a blank cell. Select that cell and click <copy then highlight all the
cells you wish to change and click Edit | Paste Special | Multiply
(check) then OK and <Esc.
Hope this helps.
