What is the greatest common factor of 12 and 36? 2 4 6 12

## Step 1<br />The greatest common factor (GCF) of two numbers is the largest number that divides both of them without leaving a remainder. <br /><br />## Step 2<br />To find the GCF of 12 and 36, we first list the factors of each number. <br /><br />### The factors of 12 are: 1, 2, 3, 4, 6, 12.<br />### The factors of 36 are: 1, 2, 3, 4, 6, 9, 12, 18, 36.<br /><br />## Step 3<br />Next, we identify the common factors of both numbers. <br /><br />### The common factors of 12 and 36 are: 1, 2, 3, 4, 6, 12.<br /><br />## Step 4<br />Finally, we select the greatest common factor from the list of common factors. <br /><br />### The greatest common factor of 12 and 36 is 12.
