Do you remember reciting your “times tables” — for example, “one seven is 7, two sevens are 14, three sevens are 21, continuing 28, 35, … and going on for ever? I have consistently replaced some digits by letters and in this way the five-figure number TIMES can be found in the times table of each of its digits but not in the times table of any other digit. On the other hand, TABLE can be found in the times table of seven different digits, each of which is a digit of TIMES or TABLE.
What number would be BEST?
