Xiao Wang said to Xiao Li, "My home phone number is seven digits, and the first four digits are 5783. Do you know what the last three digits are? " Xiao Li said, "There are too many such figures." Xiao Wang said, "It is the largest of the seven numbers that can be divisible by 2, 3 and 5 at the same time." Xiao Li thought for a long time and didn't come up with it. Can you help Xiao Li find out Xiao Wang's home phone number?
