Let's go through the process:
Add 1 to 456:
456
1
=
457
456+1=457 (does not contain the digit 4)
Add 2 to 456:
456
2
=
458
456+2=458 (does not contain the digit 4)
Add 3 to 456:
456
3
=
459
456+3=459 (does not contain the digit 4)
Add 4 to 456:
456
4
=
460
456+4=460 (contains the digit 4)
Here, adding 4 gives us 460, which includes the digit 4.
Therefore, the smallest number you can add to 456 to get a sum that uses the digit 4 is
4
