Not math's fault you forgot 1 wasn't prime. >_>
It's not terribly hard to work out even if you forget that: given you're dividing a prime number by 30, the only possible remainders are 1, 7, 11, 13, 17, 19, 23 and 29 (at which point you SHOULD notice that 1 isn't a prime), and it's really easy to prove this.

Who can say where the cloud's blowed from or who the soul'll be 'morrow? Only Sonmi the east an' the west an' the compass an' the atlas, yay, only the atlas o' clouds.
