What's the Least Common Multiple (LCM) of 24 and 30?

Answer

LCM of 24 and 30 is 120

(One hundred twenty)

Finding LCM for 24 and 30 using GCF of these numbers

The first method to find LCM for numbers 24 and 30 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:

LCM = (Number1 × Number2) ÷ GCF

GCF of numbers 24 and 30 is 6, so

LCM = (24 × 30) ÷ 6

LCM = 720 ÷ 6

LCM = 120

Finding LCM for 24 and 30 by Listing Multiples

The second method to find LCM for numbers 24 and 30 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, 144, 168

Multiples of 30: 30, 60, 90, 120, 150, 180

So the LCM for 24 and 30 is 120

Finding LCM for 24 and 30 by Prime Factorization

Another method to find LCM for numbers 24 and 30 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 30: 2, 3, 5 (exponent form: 21, 31, 51)

23 × 31 × 51 = 120
