$$\mathrm{111}+\left(\mathrm{111}\right)_{\mathrm{2}} +\left(\mathrm{111}\right)_{\mathrm{5}} +\left(\mathrm{111}\right)_{\mathrm{8}} \\ $$$$=\mathrm{111}+\left(\mathrm{1}+\mathrm{2}+\mathrm{4}\right)+\left(\mathrm{1}+\mathrm{5}+\mathrm{25}\right)+\left(\mathrm{1}+\mathrm{8}+\mathrm{64}\right) \\ $$$$=\mathrm{111}+\mathrm{7}+\mathrm{31}+\mathrm{73} \\ $$$$=\mathrm{222} \\ $$
