**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.
