    Because all digits are odd and you can't have the number 9, you can shorten down the possibilities of the number into saying that you can only use the digits 1,3,5,7. Then, because it says the smallest digit is in the thousands place, you know it starts with one. Then, because it says the greatest digit is in the ones place you know the number has to be either:

    -- 1735
    -- 1753
