How did the earliest factories multiply by the 18th century? Explain.

A series of inventions in the eighteenth century increased the efficiency of each step of the production process. They enhanced the output per worker, enabling each worker to produce more, and they made possible the production of stronger threads and yarns. Then Richard Arkwright created a cotton mill. Till this time, cloth production was spread all over the countryside and carried out within village households. But now, costly new machines could be purchased, set up and maintained in the mill.
