The sum is 154.
The largest 4-digit number possible using the digits 4, 1, 9, and 2 is 9412. To form this number, arrange the digits in descending order, starting with the highest digit. Thus, the order is 9, followed by 4, then 2, and finally 1.
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.
9,999,876 is the greatest seven-digit number using four different digits.
The smallest four-digit number not using zero is 1000. In a four-digit number, the first digit cannot be zero, so the smallest possible value for the first digit is 1. The remaining three digits can be any number from 0-9, so the smallest possible four-digit number is 1000.
The greatest possible number that a 5-digit combination can form is 99999. This is achieved by using the highest digit, 9, in each of the five places. Therefore, the largest 5-digit number is 99999.
Oh, what a happy little question! To find the smallest 6-digit number with no repeated digits, we start by using the digits 1-9 in ascending order. So, the smallest 6-digit number with no repeated digits is 123,456. Just imagine all the beautiful possibilities that number holds!
Since there are only five different digits, a 6-digit number can only be generated if a digit can be repeated. If digits can be repeated, the smallest 6-digit number is 111111.
1111, unless you allow negative number. In that case, the answer is -9999.
To find the largest three-digit even number using the digits 3, 4, and 5, you need to arrange these digits in descending order to maximize the number, ensuring that the last digit is even. The largest possible even number is 542
Assuming that the first digit of the 4 digit number cannot be 0, then there are 9 possible digits for the first of the four. Also assuming that each digit does not need to be unique, then the next three digits of the four can have 10 possible for each. That results in 9x10x10x10 = 9000 possible 4 digit numbers. If, however, you can not use the same number twice in completing the 4 digit number, and the first digit cannot be 0, then the result is 9x9x8x7 = 4536 possible 4 digit numbers. If the 4 digit number can start with 0, then there are 10,000 possible 4 digit numbers. If the 4 digit number can start with 0, and you cannot use any number twice, then the result is 10x9x8x7 = 5040 possilbe 4 digit numbers.
99 is the largest two digit number. If I can use the digits anyway I want, then 9 to the 9th power is larger
If the digits can repeat, then there are 256 possible combinations. If they can't repeat, then there are 24 possibilities.
