What's the Least Common Multiple (LCM) of 90 and 215?

Answer

LCM of 90 and 215 is 3,870

(Three thousand, eight hundred seventy)

Finding LCM for 90 and 215 using GCF of these numbers

The first method to find LCM for numbers 90 and 215 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:

LCM = (Number1 × Number2) ÷ GCF

GCF of numbers 90 and 215 is 5, so

LCM = (90 × 215) ÷ 5

LCM = 19350 ÷ 5

LCM = 3870

Finding LCM for 90 and 215 by Listing Multiples

The second method to find LCM for numbers 90 and 215 is to list out the common multiples for both numbers and pick the first one that matches:

Multiples of 90: 90, 180, 270, 360, 450, 540, 630, 720, 810, 900, 990, 1080, 1170, 1260, 1350, 1440, 1530, 1620, 1710, 1800, 1890, 1980, 2070, 2160, 2250, 2340, 2430, 2520, 2610, 2700, 2790, 2880, 2970, 3060, 3150, 3240, 3330, 3420, 3510, 3600, 3690, 3780, 3870, 3960, 4050

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

So the LCM for 90 and 215 is 3870

Finding LCM for 90 and 215 by Prime Factorization

Another method to find LCM for numbers 90 and 215 is to list all Prime Factors for both numbers and multiply the highest exponent prime factors:

All Prime Factors of 90: 2, 3, 3, 5 (exponent form: 21, 32, 51)

All Prime Factors of 215: 5, 43 (exponent form: 51, 431)

21 × 32 × 51 × 431 = 3870
