6

Explanation:

Divide each number into different multiples.
12:
- 1xx12
- 2xx6
- 3xx4

30:
- 1xx30
- 2xx15
- 3xx10
- 5xx6

The greatest common factor (the largest number that both numbers divide into evenly), is 6.
No other numbers higher than 6 in these sets can be divided from both 12 and 30 evenly.
