Answer

LCM of 66 and 243 is 5,346

(Five thousand, three hundred forty-six)

Finding LCM for 66 and 243 using GCF of these numbers

The first method to find LCM for numbers 66 and 243 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:

LCM = (Number1 × Number2) ÷ GCF

GCF of numbers 66 and 243 is 3, so

LCM = (66 × 243) ÷ 3

LCM = 16038 ÷ 3

LCM = 5346
