Correct option is A
Given:
The given numbers = 1300, 4660, and 6900.
Solution:
To find the greatest number first calculate the difference between the given numbers.
So, the numbers are 1300, 4660, 6900
=> 4660 - 1300 = 3360
=> 6900 - 4660 = 2240
=> 6900 - 1300 = 5600
Now, the HCF of Numbers N = 3360, 2240, 5600
=> N = 1120
=> Sum of the digits of N = 1 + 1 + 2 + 0
= 4
