The largest would be... 7634
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.
97531...i think? Except you forgot the fact that zero both is an even number and an odd number, so technically it should be 975310.
The largest even number that can be made with those digits is 9740 .
There are 5760 such numbers.
99999999
There is no such number. If the four digits are even, the entire number is even, not odd.
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 would be... 7634
Assign the digits from left to right, using the largest possible digit in each case. Don't forget to reserve an even digit for the last position.
Largest three digit number is 999 and we see that it is odd. One less than that is 998 and it is even and it is also three digits. No other 3 digit number is larger than 998 while being even.
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.
To form the largest four-digit even number from the digits 3, 9, 8, and 7, we need to place the largest even digit in the units place to maximize the number. The largest even digit available is 8, so it should go in the units place. The remaining digits should be arranged in descending order of magnitude to form the largest possible number, resulting in 9878.
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.
For this type of "the largest number which..." questions, you need to advance from left to right, using the largest possible digit in each case. For the first two digits, that would be 9, for the third digit (the right-most digit), the largest digit which will make this possible is an 8.
985
The largest 6 digit even number is 999998
