What is the largest odd number you can make using numbers 3456?

Answer 1

To create the largest odd number using the digits 3, 4, 5, and 6, we need to place the highest possible digit in the most significant place value. Since an odd number must end in 1, 3, 5, 7, or 9, we should place the digit 5 in the units place to ensure the number is odd. To maximize the remaining digits, we can place 6 in the hundreds place, 4 in the tens place, and 3 in the thousands place, resulting in the largest odd number 6543.
