I need more than189 do think you might now more?
It depends on how many multiples you need...
60, 120, 180, 240, 300, 360, 420, 480, 540, 600
60, 120, 180, 240, 300, 360, 420, 480, 540, 600
60, 120, 180, 240 and on and on and on and on and on and on just keep adding 60 to each multiple that you get: 180+60=240
