What's the Least Common Multiple (LCM) of 40 and 230?

Answer

LCM of 40 and 230 is 920

(Nine hundred twenty)

Finding LCM for 40 and 230 using GCF of these numbers

The first method to find LCM for numbers 40 and 230 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:

LCM = (Number1 × Number2) ÷ GCF

GCF of numbers 40 and 230 is 10, so

LCM = (40 × 230) ÷ 10

LCM = 9200 ÷ 10

LCM = 920

Finding LCM for 40 and 230 by Listing Multiples

The second method to find LCM for numbers 40 and 230 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, 720, 760, 800, 840, 880, 920, 960, 1000

Multiples of 230: 230, 460, 690, 920, 1150, 1380

So the LCM for 40 and 230 is 920

Finding LCM for 40 and 230 by Prime Factorization

Another method to find LCM for numbers 40 and 230 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 230: 2, 5, 23 (exponent form: 21, 51, 231)

23 × 51 × 231 = 920
