Finding LCM for 80 and 240 using GCF's of these numbers

The first method to find LCM for numbers 80 and 240 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:

LCM = (Number1 × Number2) ÷ GCF

GCF of numbers 80 and 240 is 80, so

LCM = (80 × 240) ÷ 80

LCM = 19200 ÷ 80

LCM = 240
