Finding LCM for 40 and 220 using GCF's of these numbers

The first method to find LCM for numbers 40 and 220 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:

LCM = (Number1 × Number2) ÷ GCF

GCF of numbers 40 and 220 is 20, so

LCM = (40 × 220) ÷ 20

LCM = 8800 ÷ 20

LCM = 440

Finding LCM for 40 and 220 by Listing Multiples
