## GCF of 12 and 36 by Long Division Method.

To find the greatest common factor (GCF) of 12 and 36 using the long division method:

**Step 1: **Start by dividing the larger number (36) by the smaller number (12).

36 ÷ 12 = 3 with a remainder of 0.

Since there is no remainder, the division process stops here.

**Step 2:** The divisors at this step, where the remainder becomes zero, is the greatest common factor (GCF).

**GCF** = 12.

Therefore, the greatest common factor (GCF) of 12 and 36 by the long division method is 12.
