Finding LCM for 54 and 81 using GCF's of these numbers

The first method to find LCM for numbers 54 and 81 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:

LCM = (Number1 × Number2) ÷ GCF

GCF of numbers 54 and 81 is 27, so

LCM = (54 × 81) ÷ 27

LCM = 4374 ÷ 27

LCM = 162
