No. The only digit of 2 is ' 2 '. It adds up to 2.
12
Yes, 321 is divisible by 3 because the sum of its digits (3 + 2 + 1) equals 6, which is a multiple of 3.
Yes, yes, and no. 3- sum of digits must be multiple of 3. 6- sum of digits must be multiple of 3 and number must be even (multiple of 2). 9- sum of digits must be multiple of 9. (The sum of the digits here is 21.)
The factors of 3 are 1 and 3. The sum of the digits of these factors is calculated as follows: for 1, the sum of its digits is 1, and for 3, the sum of its digits is 3. Therefore, the total sum of the digits of the factors of 3 is 1 + 3 = 4.
Divisibles by 3 are numbers whose individual digits evenly equal the sum of which is divisible by 3, like 3627 = 3 + 6 + 2 + 7, which equals 18.

1. its even 2.its a number 3.its pretty the sum of its digits times 2 equals 18
Yes, 321 is divisible by 3 because the sum of its digits (3 + 2 + 1) equals 6, which is a multiple of 3.
Examples: 111, 1+1+1=3; 12, 1+2=3; 30, 3+0=3.
No. Take 12 for example. 1+2=3 but 1x2 doesn't equal 3, it equals 2.

Since a dozen is 12, then the digits are 1 and 2. To get the sum, you simply add 1 + 2, which = 3.
Yes, it is. Your answer is 406. You can determine whether a number is divisible by 3 by adding the digits. If the sum of the digits (in the above, 1+2+1+8 = 12) equals 3, the number is divisible by 3.
Oh, dude, a factor of the sum of the digits being 3 or a multiple of 3 just means that if you add up all the digits in a number and it equals 3, or if that sum is a multiple of 3, then that number has a factor that fits the bill. So, like, if you have a number where the digits add up to 3, or 6, or 9, or any multiple of 3, you've got yourself a match! It's like finding a snack in your pantry that fits your cravings perfectly – it just works out, man.
A dozen is equal to 12. The sum of the digits of 12 are 1 + 2 = 3.
Yes, yes, and no. 3- sum of digits must be multiple of 3. 6- sum of digits must be multiple of 3 and number must be even (multiple of 2). 9- sum of digits must be multiple of 9. (The sum of the digits here is 21.)
24 divided by three equals 8 divided by four equals 6 2 plus 4 equals 6
