Answer:
948,762
Step-by-step explanation:
The greatest six digit number would have to start with 9. It is given that the four is in the ten thousand place. Since no number can be repeated. I put the next largest number to 9 in the thousands place which is 8. I then put 7 then 6. Since the number has to be even I put 2 since 8, 6 and 4 were already used.
