This question, as with most "odd one out" questions, requires you to second guess what was in the mind of the person who set the question.
Here are some possible answers:
1553: the only number less than 1600 = 402
1892: the only number with a digital root of 2
6397: the only number greater than 5000
3649: the only number with 4 factors
2464: the only number with 24 factors
4276: the only number with a digital root of 1.
That is six candidates out of the ten. Take your pick! Given more time, I am sure I could find good mathematical reasons why the remaining 4 are odd ones out.

To the nearest thousand, no number can round to 3600 as that is not a whole multiple of thousands - it contains hundreds which are tenths of thousands.It would have to be largest [whole] number that rounds to 3600 to the nearest hundred which would be 3649.
3649 = MMMDCXLIX
No. 3,649 is not evenly divisible by nine.
