4. (10 points) Write a three-digit number after 1220 to get a seven-digit number; if this seven-digit number is a multiple of 2014, then this three-digit number is $\qquad$ .
【Answer】Solution: Add 3 zeros after 1220, getting 1220000,

To ensure the number is a multiple of 2014, we need to add $2014-1530=484$ to 1220000.  
Therefore, the answer is: 484
