If the number is a multiple of 8 then it must be an even number, so possibilities are: 128, 146, 164 and 182. Only 128 divides evenly by 8, so that's the mystery solved!
If the number formed by the last three digits is divisible by 8. This requires that: if the digit in the hundreds place is even, the last two digits must form a number divisible by 8 and if the digit in the hundreds place is odd, the last two digits must form a number divisible by 4 but not by 8.

The question cannot be answered. All that I know about your number is that is has at least 4 digits. Your number could be a hundred digits long - I have no way of knowing.
The answer depends on which digit is 5 and what the other digits are!
