To find the greatest common factor (GCF) of 30, 18, and 12, you can use several methods. One common method is to factor each number into its prime factors and then identify the common prime factors.

Here's how you can find the prime factorization of each number:

- For 30: (30 = 2 \times 3 \times 5)
- For 18: (18 = 2 \times 3 \times 3)
- For 12: (12 = 2 \times 2 \times 3)

Now, identify the common prime factors among the three numbers, which are (2) and (3).

To find the GCF, multiply the common prime factors together:

[GCF = 2 \times 3 = 6]

So, the greatest common factor of 30, 18, and 12 is 6.
