WebDec 9, 2010 · It's clear that the fifth digit has to be 5. b, d, f and h are elements of {2,4,6,8} and the remaining a, c, g and i are elements of {1,3,7,9}. So there are at most 24 * 24 = 576 possibilities. But we can limit these possibilities drastic. 2c + d has to be divisible by 4, 4d + 20 + 4f by 6 and 2g + h by 4. WebSo it works with 3, because when you get to 12, the sum of the digits is 12-9 or 3 (which is divisible by 3). But it doesn't work with 4 because when you get to 12, you subtract 9, which isn't a multiple of 4. However this does means that if you were to use base 9, you would be able to use this trick on numbers divisible by 8 (i.e. 2, 4 and 8).
