What are the Largest 7 Digit and 8 Digit Numbers in Maths
7-digit numbers
We know that 9,99,999 is the largest 6-digit number. The successor of 9,99,999 is 9,99,999 + 1 = 10,00,000. 10,00,000 (Ten lakh) is the smallest 7-digit number. A 7-digit number begins with the ten-lakh place in the lakhs period of the place value chart. For example, a numeral 74,12,506 is read as seventy-four lakh twelve thousand five hundred six.
Periods | Lakhs | Thousands | Ones | ||||
Place | TL | L | TTh | Th | H | T | O |
Digits | 7 | 4 | 1 | 2 | 5 | 0 | 6 |
From the place value chart, it is clear that the expanded form of 74,12,506 =
7000000 + 400000 + 10000 + 2000 + 500 + 6.
We see that
Lakhs | Thousands | Ones |
7400000 | 12000 | 506 |
So, we write 7412506 in figures as 74,12,506 and in words as seventy-four lakh twelve thousand five hundred six.
8-digit numbers
The largest 7-digit number is 99,99,999. The successor of 99,99,999 = 99,99,999 + 1 = 1,00,00,000. 10000000 is the smallest 8-digit number. An 8-digit number begins with the crores place in the crores period. Let us consider an 8-digit numeral 73410568.
Periods | Crores | Lakhs | Thousands | Ones | ||||
Place | C | TL | L | TTh | Th | H | T | O |
Digits | 7 | 3 | 4 | 1 | 0 | 5 | 6 | 8 |
From the place value chart it is clear that the expanded form of 73410568 =
70000000 + 3000000 + 400000 + 10000 + 500 + 60 + 8
We see that
Crores | Lakhs | Thousands | Ones |
70000000 | 3400000 | 10000 | 568 |
So, we write 73410568 in figures as 7,34,10,568 and in words as seven crore thirty-four lakh ten thousand five hundred sixty-eight.
