Since the formulae have circular references ([Err:522](https://help.libreoffice.org/3.5/Calc/Error_Codes_in_Calc)) the spreadsheet setting needs to be changed to enable iteration (Tools > Options… > LibreOffice Calc > Calculation, tick Iterations and choose a sensible combination of `Steps:` and `Minimum change:`, <kbd>OK</kbd>). For current purposes I suggest `100` for Steps; and `0.01` for Minimum change:.

The iteration is the looping required and `Steps:` and `Minimum change:` limit the number of iterations. 

The user's difficulty might have been because of the formula error (multiply should have been divide) since, as mentioned by SO user [@tohuwawohu](https://stackoverflow.com/users/342546/tohuwawohu):
 
>it won't work for factors >=1 multiplied with B10.  I can't tell why

I don't know why either, but do remember a [bug](https://bugs.documentfoundation.org/show_bug.cgi?id=114482).
