If you want to find DC gain (Hfe) of a BJT transistor like BC547, then you need to look in its datasheet. You can easily find a datasheet for BC547 just by googling it.
Once you found it, then you will find a graph for DC current gain in the datasheet. The x-axis of the graph will be the collector current (Ic) and the y-axis will be the gain (Hfe).
As you will see from the graph the gain is dependent on the collector current Ic. Therefore first determine what collector current you want to be flowing, then use the graph to find what the DC gain will be. Then you can find what base current Ib you need to inject in order to establish the necessary collector current Ic. The relationship is Ic = Hfe*Ib.
