What's the Least Common Multiple (LCM) of 40 and 300?

Answer

LCM of 40 and 300 is 600

(Six hundred)

Finding LCM for 40 and 300 using GCF of these numbers

The first method to find LCM for numbers 40 and 300 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:

LCM = (Number1 × Number2) ÷ GCF

GCF of numbers 40 and 300 is 20, so

LCM = (40 × 300) ÷ 20

LCM = 12000 ÷ 20

LCM = 600

Finding LCM for 40 and 300 by Listing Multiples

The second method to find LCM for numbers 40 and 300 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, 600, 640, 680

Multiples of 300: 300, 600, 900, 1200

So the LCM for 40 and 300 is 600

Finding LCM for 40 and 300 by Prime Factorization

Another method to find LCM for numbers 40 and 300 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 300: 2, 2, 3, 5, 5 (exponent form: 22, 31, 52)

23 × 52 × 31 = 600
