LCM for 100 and 215

What's the Least Common Multiple (LCM) of 100 and 215?

Answer: LCM of 100 and 215 is 4,300

(Four thousand, three hundred)

Finding LCM for 100 and 215 using GCF's of these numbers

The first method to find LCM for numbers 100 and 215 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:

LCM = (Number1 × Number2) ÷ GCF

GCF of numbers 100 and 215 is 5, so

LCM = (100 × 215) ÷ 5

LCM = 21500 ÷ 5

LCM = 4300

Finding LCM for 100 and 215 by Listing Multiples

The second method to find LCM for numbers 100 and 215 is to list out the common multiples for both nubmers and pick the first which matching:

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

Multiples of 215: 215, 430, 645, 860, 1075, 1290, 1505, 1720, 1935, 2150, 2365, 2580, 2795, 3010, 3225, 3440, 3655, 3870, 4085, 4300, 4515, 4730

So the LCM for 100 and 215 is 4300

Finding LCM for 100 and 215 by Prime Factorization

Another method to find LCM for numbers 100 and 215 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 215: 5, 43 (exponent form: 51, 431)

22 × 52 × 431 = 4300
