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.

7x47

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

???057
Then just do the math to fill in the rest of the x'* and ?'*.
