Sum of 3-Digit Numbers with 1, 3, 5, 7
To find the sum of 3-digit numbers that can be formed using the digits 1, 3, 5, and 7, we need to consider all possible combinations.
Step 1: Find all possible permutations
- There are 4 digits (1, 3, 5, 7) that can be arranged in 4! = 24 ways.
- These permutations will give us all the possible 3-digit numbers.
Step 2: Calculate the sum of all permutations
- To find the sum of all these 3-digit numbers, we need to first find the sum of each digit position (hundreds, tens, ones).
- The sum of the digits in each position will be the same for all permutations since each digit is used only once.
Step 3: Calculate the total sum
- Once we have the sum of each digit position, we can calculate the total sum by multiplying the sum by the number of permutations (24).
Therefore, the sum of all 3-digit numbers that can be formed using the digits 1, 3, 5, and 7 is the total sum obtained from step 3.
By following these steps, you can efficiently calculate the sum of all possible 3-digit numbers with the given digits.
