30
Let's represent the number as "x". The given equation can be written as 2x - 12 = 30. Adding 12 to both sides, we get 2x = 42. Finally, dividing both sides by 2, we find that x = 21. So, the number is 21.
The prime factors are: 12 = 2 * 2 *3 21 = 3 *7 30 = 2 * 3 * 5 So the greatest common factor is 3.
