LCM for 9 and 24
What's the Least Common Multiple (LCM) of 9 and 24?
(Seventy-two)
Finding LCM for 9 and 24 using GCF's of these numbers
The first method to find LCM for numbers 9 and 24 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:
LCM = (Number1 × Number2) ÷ GCF
GCF of numbers 9 and 24 is 3, so
LCM = (9 × 24) ÷ 3
LCM = 216 ÷ 3
LCM = 72
Finding LCM for 9 and 24 by Listing Multiples
