What's the Least Common Multiple (LCM) of 40 and 480?

Answer

LCM of 40 and 480 is 480

(Four hundred eighty)

Finding LCM for 40 and 480 using GCF of these numbers

The first method to find LCM for numbers 40 and 480 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:

LCM = (Number1 × Number2) ÷ GCF

GCF of numbers 40 and 480 is 40, so

LCM = (40 × 480) ÷ 40

LCM = 19200 ÷ 40

LCM = 480

Finding LCM for 40 and 480 by Listing Multiples

The second method to find LCM for numbers 40 and 480 is to list out the common multiples for both numbers and pick the first one that matches:

Multiples of 40: 40, 80, 120, 160, 200, 240, 280, 320, 360, 400, 440, 480, 520, 560

Multiples of 480: 480, 960, 1440

So the LCM for 40 and 480 is 480

Finding LCM for 40 and 480 by Prime Factorization

Another method to find LCM for numbers 40 and 480 is to list all Prime Factors for both numbers and multiply the highest exponent prime factors:

All Prime Factors of 40: 2, 2, 2, 5 (exponent form: 23, 51)

All Prime Factors of 480: 2, 2, 2, 2, 2, 3, 5 (exponent form: 25, 31, 51)

25 × 51 × 31 = 480
