Answer: LCM of 9 and 47 is 423

(Four hundred twenty-three)

Finding LCM for 9 and 47 using GCF's of these numbers

The first method to find LCM for numbers 9 and 47 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:

LCM = (Number1 × Number2) ÷ GCF

GCF of numbers 9 and 47 is 1, so

LCM = (9 × 47) ÷ 1

LCM = 423 ÷ 1

LCM = 423

Finding LCM for 9 and 47 by Listing Multiples
