Greatest Number

Consider the following.

Form the greatest number using the digits 6, 3, 8, 7.

H The next greater digit is placed at tens place.

H The next greater digit is placed at hundreds place and so on.

H The greatest digit is placed at the highest place of the number.

Example : Form the greatest numbers using the given digits.

a. 8, 4, 6, 3 b. 3, 2, 6

Solution : a. We have the digits : 8, 4, 6, 3

Arrange them in descending order.

8 > 6 > 4 > 3

Hence, the greatest number is 8643.

b. We have the digits : 3, 2, 6

Arrange them in descending order.

6 > 3 > 2

Hence, the greatest number is 632.
