an easy way is to multiply 9 by factors of 10
10
100
1000
9 times 10=90
9 times 100=900
9 times 1000=9000
and so on

or you could find multipules of 9 that are over 27
multipulse are
9,18,27,36,45,54,63,72,81,90,99,108,117,126,135,144,153,162,171,180,189,198,207,216, etc
so basically you could use any number in that list from 27 and after
