Answer:
1278 × 4
Explanation:
Apparently, a 4-digit number is being multiplied by a 1-digit number. We expect that the partial products are the result of multiplying single digit numbers with different place values.
So, 4000 = 1000 × 4 or 500 × 8
800 = 200 × 4 or 100 × 8
We don't think 8 is the multiplier, because 500 and 100 have digits with the same place value multiplier (100).
Continuing, ...
280 = 70 × 4
32 = 8 × 4
The numbers being multiplied seem to be 1278 × 4.
