A number with up to 7 digits, where the first digit must be any number between 1 and 9, is known as a 7-digit number. The 7th place value of a number is called ‘Ten Lakh’ in the Indian number system and 'Million' in the International place value system. We will learn more about the 7-digit number below.
Any number that has exactly seven digits is known as a 7-digit number. The numbers that start from 1,000,000 to 9,999,999 are the 7-digit numbers. For example, 4,567,890 and 7,123,456 are 7-digit numbers.
The 7-digit number can be written in two different systems, they are: International number system and Indian number system In the international number system, we put commas after every 3 digits, starting from the right.
For example, the smallest 7-digit number is written as 1,000,000. This number is called one million because the first comma from the right marks the million place.
In the Indian number system, we put the first comma after 3 digits from the right, and then after every 2 digits.
Example: The smallest 7-digit number is written as 10,00,000. This number is called 10 lakh because the first comma from the right indicates the lakh place.
The charts given below show the difference between the numbers up to 7 digits according to the Indian place value chart and the International place value chart.
Any 7-digit number has place values that can go up to one million in the International system or ten lakh in the Indian system. Here are the place value names from right to left in a 7-digit number.
Digit 1: Ones / Units
Digit 2: Tens
Digit 3: Hundreds
Digit 4: Thousands
Digit 5: Ten Thousands
Digit 6: Lakhs / Hundred Thousands
Digit 7: Ten Lakhs / Million
Let us take an example number: 6,543,210 and break it into its place values.
Digit 1: PV = 0 × 1 = 0
Digit 2: PV = 1 × 10 = 10
Digit 3: PV = 2 × 100 = 200
Digit 4: PV = 3 × 1,000 = 3,000
Digit 5: PV = 4 × 10,000 = 40,000
Digit 6: PV = 5 × 100,000 = 500,000
Digit 7: PV = 6 × 1,000,000 = 6,000,000
Here, PV stands for Place Value. Largest 7-Digit Number The biggest 7-digit number is 9,999,999. If we add one more number, we will get 10,000,000, which has 8 digits.
Smallest 7-Digit Number The smallest 7-digit number is 1,000,000. If we subtract 1 from this number, we will get 999,999, which has only 6 digits.
7-digit numbers may look big, but they still follow a simple pattern. By understanding the number systems, place values, and easy tricks, you can read, write, and compare them quickly. These tips will help you work with large numbers without confusion.
Students sometimes make mistakes when learning or writing numbers, especially when it is a big number like a 7-digit number. A small mistake in reading, writing, or placing commas can completely change the number. Given below are some common errors and how to avoid them.
Write the smallest 7-digit number in the Indian number system.
10,00,000
In the Indian number system, we place commas after 3 digits from the right, and then every 2 digits. This gives 10,00,000, which is called ten lakh.
What is the place value of 5 in the number 5,432,198?
The place value is 5,000,000
The first digit from the left in a 7-digit number is in the million place according to the international system. Here, 5 is in the million place, so its place value is 5 × 1,000,000 = 5,000,000.
Write 12,34,567 in the International number system
1,234,567
In the Indian system, commas are placed in the 3-2-2 pattern. To convert that to the International system, we place commas after every 3 digits from the right. Therefore, it becomes 1,234,567.
Which is greater: 7,65,432 or 10,00,000?
10,00,000
10,00,000 is a 7-digit number, while 7,65,432 is a 6-digit number. Hence, 10,00,000 is larger.
How many 7-digit numbers are there in total?
9,000,000
The smallest 7-digit number is 1,000,000 and the largest is 9,999,999. We can find the total numbers by:
Number of 7-digit numbers = Largest - Smallest + 1 = 9,999,999 - 1,000,000 + 1 = 9,000,000
