Finding GCF: Step 1: List PF. Step 2: Identify common factors. Step 3: Multiply the common factors.

Finding LCM:

Step 1: List PF. Step 2: Identify the factors in common. If a factor appears in more than one number, count it the greatest number of times it occurs. Step 3: Multiply the factors.

Reducing to lowest terms: Step 1: List PF. Step 2: Cross out the common factors. Step 3: Remaining factors are the numerator and denominator of the lowest terms fraction. (If there is more than one factor in the numerator or denominator, multiply those factors.

2 occurs three times, so multiply it three times when finding the LCM
