Writing the given numbers in the Indian place value chart:
| Places | Crores | Ten Lakhs | Lakhs | Ten Thousands | Thousands | Hundreds | Tens | Ones |
|---|---|---|---|---|---|---|---|---|
| 36951 | 3 | 6 | 9 | 5 | 1 | |||
| 37140 | 3 | 7 | 1 | 4 | 0 | |||
| 723891 | 7 | 2 | 3 | 8 | 9 | 1 | ||
| 732142 | 7 | 3 | 2 | 1 | 4 | 2 | ||
| 5718901 | 5 | 7 | 1 | 8 | 9 | 0 | 1 | |
| 37401 | 3 | 7 | 4 | 0 | 1 |
Out of the given numbers, three are 5-digit, two are 6-digit and one is 7-digit.
7-digit number i.e. 5718901 is the largest.
For the 6-digit numbers 723891 and 732142:
Comparing them: lakhs 7 = 7, ten thousands 2 < 3. So 732142 > 723891.
For the 5-digit numbers 36951, 37140 and 37401:
Comparing 36951 and 37140: ten thousands 3 = 3, thousands 6 < 7. So 36951 < 37140.
Comparing 37140 and 37401: ten thousands 3 = 3, thousands 7 = 7, hundreds 1 < 4. So 37140 < 37401.
So among the 5-digit numbers, 37401 is largest, then 37140, then 36951.
Hence, the descending order is: 5718901 > 732142 > 723891 > 37401 > 37140 > 36951.
