Answer:

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.
