Which number is the odd one out? (and why)

6467, 9455, 7568, 3124, 9364

nobody gets anything but my respect for this one

It could be "6467" because it cannot be divided by 2 or 5
It could be "9455" because it is the only number ending with 2 same digits "5 5"
it could be "7568" because all others are approximately 3000 multiplied by 1, 2 or 3
It could be "3124" because the sum of 3+1+2+4 is the lowest (or because the number is the lowest)
It could be "9364" because it's the only number last digit is lower than the pre-last.

I copied and pasted this answer from google...

I'm not responsible for any any grammatical errors....

6467

The first and last numbers do not multiply to form the middle two numbers.

Wow. What an exciting contest. Too bad I didn't see it earlier.
