What's the Least Common Multiple (LCM) of 18 and 24?

Answer: LCM of 18 and 24 is 72

(Seventy-two)

Finding LCM for 18 and 24 using GCF's of these numbers

The first method to find LCM for numbers 18 and 24 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:

LCM = (Number1 × Number2) ÷ GCF

GCF of numbers 18 and 24 is 6, so

LCM = (18 × 24) ÷ 6

LCM = 432 ÷ 6

LCM = 72

Finding LCM for 18 and 24 by Listing Multiples

The second method to find LCM for numbers 18 and 24 is to list out the common multiples for both nubmers and pick the first which matching:

Multiples of 18: 18, 36, 54, 72, 90, 108

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

So the LCM for 18 and 24 is 72

Finding LCM for 18 and 24 by Prime Factorization

Another method to find LCM for numbers 18 and 24 is to list all Prime Factors for both numbers and multiply the highest exponent prime factors:

All Prime Factors of 18: 2, 3, 3 (exponent form: 21, 32)

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

23 × 32 = 72
