Nan Nan and Bin Bin calculated the same calculation problem of multiplying a three-digit number and a two-digit number, but they both made a mistake. Nan Nan wrote a 4 for the 7 in the ones place of the three-digit number, and the result was 4860. Bin Bin mistakenly wrote 2 in the three tens digits as 8, and the result was 5805. What should be the correct product?
楠楠和彬彬计算同一道三位数和两位数相乘的计算题，结果两个人都做错了，楠楠把三位数个位上的7错写成了4，结果得4860，彬彬把三位数十位上的2错写成了8，结果得5805．正确的乘积应是多少？
