I would like to know why my four gear motors are rotating at different speeds when connected to 2 L293D motor drivers, controlled by the arduino

Ignore direction of the motors(for now). This is my connection diagram. Any and all improvements to this are welcome. Bottom left motor seems to run at 210-224 rpm Bottom right motor runs at 160-180 rpm Top right motor runs at 210-224 rpm Top left…
