37, 74, 111, 148, 185, 222, 259, 296, 333, 370, 407, 444.
37, 74, 111, 148, 185, 222, 259, 296, 333, 370 . . .
Well, honey, the greatest common factor of 333 and 1000 is 1. Those numbers don't have any common factors other than 1 because 333 is a prime number and 1000 is just a bunch of 2s and 5s. So, there you have it, the greatest common factor is a big ol' 1.
