Answer:
First of all, I think you meant nearest. Second of all, the answer is 560,000. The reason I know this is because of a rhyme, the rhyme says "Five or above, give it a shove. Four or below, let it go." and what that means is, if the number next to the number you are rounding to is a number between 5 and 9, round it up. On the other hand if the number is a number between 1 and 4, just put zeros after it instead of rounding it up and putting zeros behind it.
