What's the Least Common Multiple (LCM) of 24 and 9?

Answer

LCM of 24 and 9 is 72

(Seventy-two)

Finding LCM for 24 and 9 using GCF of these numbers

The first method to find LCM for numbers 24 and 9 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:

LCM = (Number1 × Number2) ÷ GCF

GCF of numbers 24 and 9 is 3, so

LCM = (24 × 9) ÷ 3

LCM = 216 ÷ 3

LCM = 72

Finding LCM for 24 and 9 by Listing Multiples

The second method to find LCM for numbers 24 and 9 is to list out the common multiples for both numbers and pick the first one that matches:

Multiples of 24: 24, 48, 72, 96, 120

Multiples of 9: 9, 18, 27, 36, 45, 54, 63, 72, 81, 90

So the LCM for 24 and 9 is 72

Finding LCM for 24 and 9 by Prime Factorization

Another method to find LCM for numbers 24 and 9 is to list all Prime Factors for both numbers and multiply the highest exponent prime factors:

All Prime Factors of 24: 2, 2, 2, 3 (exponent form: 23, 31)

All Prime Factors of 9: 3, 3 (exponent form: 32)

23 × 32 = 72
