There are 8 possible numbers.
The last digit can be 1 or 7 since the number is odd.
The first digit can be any of the three except 0 since then it would not
be a 4 digit number, but once you pick the last digit, there are really only 2 numbers left for the first digit.
So let's use 1 as the last digit
the numbers are
7401, 7041, 4701, 4071.
Now use 7 as the last digit.
We have 1407, 1047, 4107, 4017.
So the 8 numbers are:
7401, 7041, 4701, 4071,1407, 1047, 4107, 4017
( the number of possible numbers is 8 since that is 23 . There are 2 choices for
the last digit, the once we pick that 2 choices for the first digit. For either of the remaining two digits there are 2 choices and then the last digit is fixed.)
