Firstly I found my number closest to 5000 and got 5001.
Next I worked out the smallest multiple;e of 5 because it needs certain numbers and I got 1235.
Next for the same reasons I did the largest multiple of 3 and I got 6432.
Then using my remaining numbers I made the largest odd number 9867 and got the largest even number 9874.
