LCM for 8 and 24
What's the Least Common Multiple (LCM) of 8 and 24?
(Twenty-four)
Finding LCM for 8 and 24 using GCF's of these numbers
The first method to find LCM for numbers 8 and 24 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:
LCM = (Number1 × Number2) ÷ GCF
GCF of numbers 8 and 24 is 8, so
LCM = (8 × 24) ÷ 8
LCM = 192 ÷ 8
LCM = 24
Finding LCM for 8 and 24 by Listing Multiples
