What's the Least Common Multiple (LCM) of 100 and 405?

Answer

LCM of 100 and 405 is 8,100

(Eight thousand, one hundred)

Finding LCM for 100 and 405 using GCF of these numbers

The first method to find LCM for numbers 100 and 405 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:

LCM = (Number1 × Number2) ÷ GCF

GCF of numbers 100 and 405 is 5, so

LCM = (100 × 405) ÷ 5

LCM = 40500 ÷ 5

LCM = 8100

Finding LCM for 100 and 405 by Listing Multiples

The second method to find LCM for numbers 100 and 405 is to list out the common multiples for both numbers and pick the first one that matches:

Multiples of 100: 100, 200, 300, 400, 500, 600, 700, 800, 900, 1000, 1100, 1200, 1300, 1400, 1500, 1600, 1700, 1800, 1900, 2000, 2100, 2200, 2300, 2400, 2500, 2600, 2700, 2800, 2900, 3000, 3100, 3200, 3300, 3400, 3500, 3600, 3700, 3800, 3900, 4000, 4100, 4200, 4300, 4400, 4500, 4600, 4700, 4800, 4900, 5000, 5100, 5200, 5300, 5400, 5500, 5600, 5700, 5800, 5900, 6000, 6100, 6200, 6300, 6400, 6500, 6600, 6700, 6800, 6900, 7000, 7100, 7200, 7300, 7400, 7500, 7600, 7700, 7800, 7900, 8000, 8100, 8200, 8300

Multiples of 405: 405, 810, 1215, 1620, 2025, 2430, 2835, 3240, 3645, 4050, 4455, 4860, 5265, 5670, 6075, 6480, 6885, 7290, 7695, 8100, 8505, 8910

So the LCM for 100 and 405 is 8100

Finding LCM for 100 and 405 by Prime Factorization

Another method to find LCM for numbers 100 and 405 is to list all Prime Factors for both numbers and multiply the highest exponent prime factors:

All Prime Factors of 100: 2, 2, 5, 5 (exponent form: 22, 52)

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

22 × 52 × 34 = 8100
