Puzzle Corner – Opening the Safe


We could really do with your help on this one because we've lost the combination to the Motor Technology safe and we need someone good with numbers to work it out for us. So here are some clues and all we can remember about the combination:

  • We know that the combination number is made up of four digits, so 6789, or 4321
  • We can remember that all the digits in the number are different
  • It begins and ends with odd numbers but the two numbers in the middle are even
  • It is divisible by the numbers 19 and 519 exactly
