Comparison of Numbers

You already know how to compare numbers upto four digits. Let’s now learn how to compare
numbers with five or six digits.

Comparison of numbers with different number of digits

If two numbers have different number of digits, the number with more digits is greater.

Consider the numbers 1,34,791 and 8,264.

The number of digits in 1,34,791 = 6 and in 8,264 = 4
Since 6 > 4, therefore, 1,34,791 > 8,264.

Comparison of numbers with the same number of digits

1. Compare the face values of the leftmost digits, i.e., the digits at the lakhs place.

L TTh Th H T O Remember

7 9 2 8 4 3 To compare numbers

8 0 7 6 4 2 having the same number of
digits, always start from the

8 > 7 leftmost digit.
So, 8,07,642 > 7,92,843.

2. If the face values of the digits at the lakhs place are the same, then compare the face
values of the digits at the ten thousands place.

L TTh Th H T O

7 9 2 8 4 3
Same
7 6 3 2 1 4

9 > 6

So, 7,92,843 > 7,63,214.
3. If the face values of the digits at the lakhs and ten thousands place are the same, then
compare the face values of the digits at the thousands place.

L TTh Th H T O

7 9 2 8 4 3

7 9 3 2 1 4

Same 3 > 2

So, 7,93,214 > 7,92,843.
