Question
Find the difference between the greatest and the least 5-digit number that can be written using the digits 6, 2, 7, 4, and 3 each only once.
Solution
Given numbers = 6, 2, 7, 4, 3
To make the greatest number by combining these digits, the given digits are written in descending order like = 76,432
To make the smallest number by combining these digits, the given digits are written in increasing order like = 23,467.
Hence difference of two numbers = bigger number − smaller number
= 76,432 − 23,467
= 52,965
The difference between the greatest and smallest numbers formed from the given digits will be 52,965.
