You weren't suppose to ask that
Just by looking it was easy to see the last digit of the first number would be 1. That got us down to needing 2 digits or 99 possibilites. I got stuck there and just made a spread sheet that multiplied 1001 - 1999 x 417 and looked for the answer. In other words - I cheated.

You just set it up like a normal multipication problem
_1???
_x417
xxxxx
xxxx0
xxx00
???57

Then you know that top right ? has to be a 1 to make ???57 then keeping goin you know:
_1??1
_x417
xxxx7
xxx10
xxx00
???57

Then that secnod ? from the top right has to be a 2 the make the 4+1=5 in the answer:

_1?21
_x417
xxx47
xxx10
xxx00
???57

And you just keep goin

1??1
X 417
-----------
7x47
1xx10
4xx400
------------
???057

So, we know 7x47, so we get 1?21, and then 1x210



1?21
X 417
-----------
x7x47
x1x210
4xx400
------------
???057

So, 10-4-2=4, then we have 7447, that makes 1921,

1921
X 417
-----------
x7x47
x1x210
4xx400
------------
???057

Then just do the math to fill in the rest of the x'* and ?'*.
