If you ask for the highest common factor, then you only get one of them. If
I gave you two of them and told you that they're both the highest, then you'd
ask me which one is the bigger highest and which one is the smaller highest.
All of the common factors of 12, 18, 24, and 30 are: 1, 2, 3, and 6 .
The highest one is 6 .
