The Qingliang Electric Fan Branch had a large number of production orders in June, and the employees did not have holidays throughout the month. From the first day, the same number of workers were sent from the main factory to work in the branch every day. By the end of the month, there were only 250 workers left in the main factory. If at the end of the month, the total workload of workers in the main factory is 8,805 working days (one day for one person is one working day), and no one is absent from work, then how many workers are sent by the main factory to work in the branch this month?
清凉电扇分厂6月份生产订单较多，职工全月不放假，而且从第一天起，每天都从总厂陆续派相同人数的工人到分厂工作，直至月底，总厂还剩250人．如果月底统计总厂工人的工作量是8805个工作日(1人1天为一个工作日)，并且无人缺勤，那么这个月由总厂派分厂工作的工人共有多少人？
