The product divisible by 6 is definitely divisible by 6, so 6 and 12 multiplied by other numbers are definitely divisible by 6, so there are 26- 1=25 kinds of * *- 1 which is 6* 12, and then 2*3=6, so there are multiples of 2*3. Multiply of 2 * Multiply of 3 = Multiply of 6 * * has 4*6-2 1=3 (why -2, -3, -2 1 extrapolation), and finally there are 2+3+25+3=33 multiples of 6 (I haven't forgotten for a long time. ...
