What's the Least Common Multiple (LCM) of 24 and 80?

Answer: LCM of 24 and 80 is 240

(Two hundred forty)

Finding LCM for 24 and 80 using GCF's of these numbers

The first method to find LCM for numbers 24 and 80 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:

LCM = (Number1 × Number2) ÷ GCF

GCF of numbers 24 and 80 is 8, so

LCM = (24 × 80) ÷ 8

LCM = 1920 ÷ 8

LCM = 240

Finding LCM for 24 and 80 by Listing Multiples

The second method to find LCM for numbers 24 and 80 is to list out the common multiples for both nubmers and pick the first which matching:

Multiples of 24: 24, 48, 72, 96, 120, 144, 168, 192, 216, 240, 264, 288

Multiples of 80: 80, 160, 240, 320, 400

So the LCM for 24 and 80 is 240

Finding LCM for 24 and 80 by Prime Factorization

Another method to find LCM for numbers 24 and 80 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 80: 2, 2, 2, 2, 5 (exponent form: 2⁴, 5¹)

2⁴ × 3¹ × 5¹ = 240
