A number with multiples 10 and 5 would not have a factor of 12. A single mystery number would not have a sum of 6. Under these conditions, the mystery number will remain a mystery.

What is a factor of the sum of the digits equals 3 or a multiple of 3?
If that is the case, then three is a factor of the original number.

How do you know if a number is a factor of 9?
I think you might mean "multiple." If the sum of a number's digits is a multiple of 9, the original number is as well. If you want to know how you know if a number is a factor of 9, memorize the numbers 1, 3 and 9.
What is the number of these clues the mystery number has three digits the number is a multiple of 8 the hundreds digit is 1 the sum of the numbers digit is 11?
If the number is a multiple of 8 then it must be an even number, so possibilities are: 128, 146, 164 and 182. Only 128 divides evenly by 8, so that's the mystery solved!
Is 189 a prime or composite number?
189 is a composite. Some quick tests, which can be done in your head: Check if the number is even (2 is a factor). Ones place will have 0,2,4,6, or 8 if even. Multiple of 5 (5 is a factor): Ones digit is 0 or 5. Multiple of 3 or 9: Add up the digits in the number; if this sum is 3 or a multiple of 3, then the original number is a multiple of 3 (3 is a factor). Additionally, if this sum equals 9 or a multiple of 9, then 9 is a factor. This is the case for 189 : 1+8+9=18, which is a multiple of 9. Since we found a factor (in addition to 1 & the original number) then the number is composite and not prime.
Which numbers are multiples of 6?
There are an infinite number of multiples of 6 (numbers that six can divide into evenly with no remainder). Without using a calculator, you can determine if a number is a multiple of 6. To be a multiple of 6, it must have both 3 and 2 as factors. So if the number is even, then 2 is a factor. To determine if it is even, look at the ones digit, and if it is (0,2,4,6, or 8) then it's even. Then to determine if 3 is a factor, add the digits in the number, if this sum is a multiple of 3, then the number is also a multiple of 3 (or you could say 3 is a factor). If both of these are true, then the number is a multiple of 6. Example: 984: Last digit (ones digit) is 4, so it's even. Sum 9+8+4=21, which is a multiple of 3, so the number is a multiple of 3. Therefore it is a multiple of 6.
