LCM for 72 and 96
What's the Least Common Multiple (LCM) of 72 and 96?
(Two hundred eighty-eight)
Finding LCM for 72 and 96 using GCF's of these numbers
The first method to find LCM for numbers 72 and 96 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:
LCM = (Number1 × Number2) ÷ GCF
GCF of numbers 72 and 96 is 24, so
LCM = (72 × 96) ÷ 24
LCM = 6912 ÷ 24
LCM = 288
Finding LCM for 72 and 96 by Listing Multiples
