Answer :

Sure, let's go through each number and insert commas where appropriate. Commas are typically used to separate groups of three digits, starting from the right.

a. 13886
To insert commas, start from the rightmost side:
- '13,886'

b. 365
This number is already less than a thousand, so no commas are needed:
- '365'

c. 719463
Starting from the right, group every three digits:
- '719,463'

d. 40047209
Again, start from the right and add commas every third digit:
- '40,047,209'

e. 2145739180
Separate every three digits starting from the right:
- '2,145,739,180'

f. 1783457
Add commas for every three digits from the right:
- '1,783,457'

These are the numbers formatted with commas inserted to help with readability.
