Finding LCM for 18 and 180 using GCF's of these numbers

The first method to find LCM for numbers 18 and 180 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:

LCM = (Number1 × Number2) ÷ GCF

GCF of numbers 18 and 180 is 18, so

LCM = (18 × 180) ÷ 18

LCM = 3240 ÷ 18

LCM = 180
