What's the Least Common Multiple (LCM) of 10 and 405?

Answer

LCM of 10 and 405 is 810

(Eight hundred ten)

Finding LCM for 10 and 405 using GCF of these numbers

The first method to find LCM for numbers 10 and 405 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:

LCM = (Number1 × Number2) ÷ GCF

GCF of numbers 10 and 405 is 5, so

LCM = (10 × 405) ÷ 5

LCM = 4050 ÷ 5

LCM = 810

Finding LCM for 10 and 405 by Listing Multiples

The second method to find LCM for numbers 10 and 405 is to list out the common multiples for both numbers and pick the first one that matches:

Multiples of 10: 10, 20, 30, 40, 50, 60, 70, 80, 90, 100, 110, 120, 130, 140, 150, 160, 170, 180, 190, 200, 210, 220, 230, 240, 250, 260, 270, 280, 290, 300, 310, 320, 330, 340, 350, 360, 370, 380, 390, 400, 410, 420, 430, 440, 450, 460, 470, 480, 490, 500, 510, 520, 530, 540, 550, 560, 570, 580, 590, 600, 610, 620, 630, 640, 650, 660, 670, 680, 690, 700, 710, 720, 730, 740, 750, 760, 770, 780, 790, 800, 810, 820, 830

Multiples of 405: 405, 810, 1215, 1620

So the LCM for 10 and 405 is 810

Finding LCM for 10 and 405 by Prime Factorization

Another method to find LCM for numbers 10 and 405 is to list all Prime Factors for both numbers and multiply the highest exponent prime factors:

All Prime Factors of 10: 2, 5 (exponent form: 21, 51)

All Prime Factors of 405: 3, 3, 3, 3, 5 (exponent form: 34, 51)

21 × 51 × 34 = 810
