The largest three-digit even number that can be formed using the digits 3, 4, and 5 is 543. To determine this, we need to consider the possible arrangements of the digits. Since we want to create an even number, the last digit must be 4. The largest possible number for the hundreds place is 5, and the remaining digit, 3, goes in the tens place. Therefore, the largest three-digit even number using the digits 3, 4, and 5 is 543.

The largest even number less than 400,000,000 that can be formed using the digits 1 through 9 only once is 398,765,412. This number uses each of the digits from 1 to 9 exactly once and ends with the digit 2, making it even. Other combinations either exceed 400,000,000 or do not use all the digits exactly once.
97632 is the largest number containing these digits. To make the largest number simply order the numbers in descending order. As it happens this results in an even number so nothing further is necessary.
