LCM for 20 and 230

What's the Least Common Multiple (LCM) of 20 and 230?

Answer: LCM of 20 and 230 is 460

(Four hundred sixty)

Finding LCM for 20 and 230 using GCF's of these numbers

The first method to find LCM for numbers 20 and 230 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:

LCM = (Number1 × Number2) ÷ GCF

GCF of numbers 20 and 230 is 10, so

LCM = (20 × 230) ÷ 10

LCM = 4600 ÷ 10

LCM = 460

Finding LCM for 20 and 230 by Listing Multiples

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

Multiples of 230: 230, 460, 690, 920

So the LCM for 20 and 230 is 460

Finding LCM for 20 and 230 by Prime Factorization

Another method to find LCM for numbers 20 and 230 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 230: 2, 5, 23 (exponent form: 21, 51, 231)

22 × 51 × 231 = 460
