Finding LCM for 24 and 84 using GCF's of these numbers

The first method to find LCM for numbers 24 and 84 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:

LCM = (Number1 × Number2) ÷ GCF

GCF of numbers 24 and 84 is 12, so

LCM = (24 × 84) ÷ 12

LCM = 2016 ÷ 12

LCM = 168
