What's the Least Common Multiple (LCM) of 20 and 29?

Answer

LCM of 20 and 29 is 580

(Five hundred eighty)

Finding LCM for 20 and 29 using GCF of these numbers

The first method to find LCM for numbers 20 and 29 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:

LCM = (Number1 × Number2) ÷ GCF

GCF of numbers 20 and 29 is 1, so

LCM = (20 × 29) ÷ 1

LCM = 580 ÷ 1

LCM = 580

Finding LCM for 20 and 29 by Listing Multiples

The second method to find LCM for numbers 20 and 29 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

Multiples of 29: 29, 58, 87, 116, 145, 174, 203, 232, 261, 290, 319, 348, 377, 406, 435, 464, 493, 522, 551, 580, 609, 638

So the LCM for 20 and 29 is 580

Finding LCM for 20 and 29 by Prime Factorization

Another method to find LCM for numbers 20 and 29 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 29: 29 (exponent form: 291)

22 × 51 × 291 = 580
