To form the largest number, arrange the digits in descending order (decreasing order of numbers).
As, 8 > 6 >4 >3 > 2 > 1 > 0
Therefore, the largest number is 8,64,32,100
To form the smallest number, arrange the digits in ascending order (increasing order of numbers).
As, 0 < 1 < 2 < 3 < 4 < 6 < 8
As a number cannot start with 0, start the number with the next smallest value followed by 0.
Therefore, the smallest number is 1,00,23,468.
