LCM for 9 and 49

What's the Least Common Multiple (LCM) of 9 and 49?

Answer: LCM of 9 and 49 is 441

(Four hundred forty-one)

Finding LCM for 9 and 49 using GCF's of these numbers

The first method to find LCM for numbers 9 and 49 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:

LCM = (Number1 × Number2) ÷ GCF

GCF of numbers 9 and 49 is 1, so

LCM = (9 × 49) ÷ 1

LCM = 441 ÷ 1

LCM = 441

Finding LCM for 9 and 49 by Listing Multiples
