**Solution:**

We will be using the concepts of whole numbers and the subtraction of numbers to solve the given problem.

Here we will use comparing numbers method. 6, 2, 7, 4, 3 are the digits to be used to form the greatest and the least 5-digit number.

To write the greatest 5-digit number, the digits 6, 2, 7, 4, 3 needs to be written in descending order. Hence, 76432 is the greatest 5-digit number.

To write the smallest 5-digit number, the digits 6, 2, 7, 4, 3 needs to be written in ascending order. Hence, 23467 is the least 5-digit number.

Difference between the two numbers = 76432 – 23467 = 52965

Thus, the difference between the two numbers is 52965.
