What's the Least Common Multiple (LCM) of 20 and 430?

Answer

LCM of 20 and 430 is 860

(Eight hundred sixty)

Finding LCM for 20 and 430 using GCF of these numbers

The first method to find LCM for numbers 20 and 430 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:

LCM = (Number1 × Number2) ÷ GCF

GCF of numbers 20 and 430 is 10, so

LCM = (20 × 430) ÷ 10

LCM = 8600 ÷ 10

LCM = 860

Finding LCM for 20 and 430 by Listing Multiples

The second method to find LCM for numbers 20 and 430 is to list out the common multiples for both numbers and pick the first one that matches:

Multiples of 20: 20, 40, 60, 80, 100, 120, 140, 160, 180, 200, 220, 240, 260, 280, 300, 320, 340, 360, 380, 400, 420, 440, 460, 480, 500, 520, 540, 560, 580, 600, 620, 640, 660, 680, 700, 720, 740, 760, 780, 800, 820, 840, 860, 880, 900

Multiples of 430: 430, 860, 1290, 1720

So the LCM for 20 and 430 is 860

Finding LCM for 20 and 430 by Prime Factorization

Another method to find LCM for numbers 20 and 430 is to list all Prime Factors for both numbers and multiply the highest exponent prime factors:

All Prime Factors of 20: 2, 2, 5 (exponent form: 22, 51)

All Prime Factors of 430: 2, 5, 43 (exponent form: 21, 51, 431)

22 × 51 × 431 = 860
