Brainteasing

I once got tripped up by a particularly diabolical "you'll feel stupid if you don't figure it out"-type brainteaser once. My dad showed it to me in a magazine. There was this Venn diagram, two overlapping circles, containing three sets of numbers, something like this:
      ____    ___
     /    \  /   \
   /   6   /\  156 \
 /  4884 /    \ 713 \
|  1771 |  535 | 278 |
| 29592 |  707 | 350 |
|    33 |  474 | 904 |
| 98089 |  212 | 127 |
 \ 64046 \    / 209 /
   \  7227 \/ 384  /
     \____/  \___/


You had to figure out the property shared by the numbers in each circle (the numbers inside the overlap, of course, had both properties).
