Since a dozen is 12, then the digits are 1 and 2. To get the sum, you simply add 1 + 2, which = 3.
When the sum of the digits you are adding is 10 or larger.
The sum of the digits is also a multiple of 9. And, if the sum of the digits is too large, you can sum those digits and keep going.
Add the digits together. The sum of the digits of 23 is 5.
There are several hundred of them. One example, the smallest, is 1039

The sum of a dozen is twelve.
12 is dozen.......so 2
the sum of the digits one hundred and twenty six is 9!!
the sum of my digits is 6? answer=60

Add the digits together. The sum of the digits of 23 is 5.
It is 45.
One possibility is 11111222223333344444
Start with the smallest multiple of 13 and continue with the next smallest until finding one that fits the specifications. 13, sum of digits is 1 + 3 = 4 which is not prime 26, sum of digits is 2 + 6 = 8 which is not prime 39, sum of digits is 3 + 9 = 12 which is not prime 52, sum of digits is 5 + 2 = 7 which is prime So, 52 is the smallest positive multiple of 13 for which the sum of its digits is prime.
It's not entirely clear from the wording of your question what it is you want to know. Seven is a one-digit number. The sum of its digits is 7. Seven has two factors: 1 and 7. That sum is 8.
