What's the Least Common Multiple (LCM) of 80 and 144?

Answer

LCM of 80 and 144 is
720

(Seven hundred twenty)

Finding LCM for 80 and 144 using GCF of these numbers

The first method to find LCM for numbers 80 and 144 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:

LCM = (Number1 × Number2) ÷ GCF

GCF of numbers 80 and 144 is 16, so

LCM = (80 × 144) ÷ 16

LCM = 11,520 ÷ 16

LCM = 720

Finding LCM for 80 and 144 by Listing Multiples

The second method to find LCM for numbers 80 and 144 is to list out the common multiples for both numbers and pick the first one that matches:

Multiples of 80: 80, 160, 240, 320, 400, 480, 560, 640, 720, 800, 880

Multiples of 144: 144, 288, 432, 576, 720, 864, 1,008

So the LCM for 80 and 144 is 720

Finding LCM for 80 and 144 by Prime Factorization

Another method to find LCM for numbers 80 and 144 is to list all Prime Factors for both numbers and multiply the highest exponent prime factors:

All Prime Factors of 80: 2, 2, 2, 2, 5 (exponent form: 24, 51)

All Prime Factors of 144: 2, 2, 2, 2, 3, 3 (exponent form: 24, 32)

24 × 51 × 32 = 720
