use 6 of the digits from 1 to 9 to make each number. use each digit only once.
the least possible odd number
123,457
would 123457 do it?
To find the least possible odd number using 6 digits from 1 to 9, we must consider the properties of odd numbers.
First, let's understand the properties of odd numbers. Odd numbers are not divisible by 2 and end with the digits 1, 3, 5, 7, or 9.
From the given digits (1 to 9), five of them are odd (1, 3, 5, 7, 9) and four of them are even (2, 4, 6, 8).
To create the least possible odd number, we need to ensure two things:
1. The resulting number should be as small as possible.
2. The resulting number should be odd.
To achieve the above, we can follow this approach:
1. Place the smallest odd digit (1) in the units place since it will make the number smallest.
2. As we need to use 6 digits, let's use the next 5 smallest odd digits (3, 5, 7, 9) from left to right.
Using this approach, the least possible odd number created from 6 digits from 1 to 9 is 13579.
