98
The largest two-digit even number is 98. In the decimal system, each digit can range from 0 to 9, but for a two-digit number, the first digit cannot be zero. Since we are looking for an even number, the last digit must be an even number, which leaves us with 0, 2, 4, 6, or 8. Among these options, 8 is the largest even digit, resulting in 98 as the largest two-digit even number.

To form the largest even number, the last digit must be even, which means it can be either 8, 4, or 2. Placing the largest even digit, 8, in the ones place, we can continue selecting the next largest digits in descending order until all digits are used.
To be an even number then the final digit = 2. The largest single prime digit is 7 (as both 8 and 9 are composite). The greatest even number fulfilling the conditions is 77777772.
No, in order for the number to be even, the last number must be a multiple of 2. It doesn't matter what the largest number is as long as the last number is a multiple of two.
