What's the Least Common Multiple (LCM) of 90 and 205?

Answer

LCM of 90 and 205 is 3,690

(Three thousand, six hundred ninety)

Finding LCM for 90 and 205 using GCF of these numbers

The first method to find LCM for numbers 90 and 205 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:

LCM = (Number1 × Number2) ÷ GCF

GCF of numbers 90 and 205 is 5, so

LCM = (90 × 205) ÷ 5

LCM = 18450 ÷ 5

LCM = 3690

Finding LCM for 90 and 205 by Listing Multiples

The second method to find LCM for numbers 90 and 205 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

Multiples of 205: 205, 410, 615, 820, 1025, 1230, 1435, 1640, 1845, 2050, 2255, 2460, 2665, 2870, 3075, 3280, 3485, 3690, 3895, 4100

So the LCM for 90 and 205 is 3690

Finding LCM for 90 and 205 by Prime Factorization

Another method to find LCM for numbers 90 and 205 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 205: 5, 41 (exponent form: 51, 411)

21 × 32 × 51 × 411 = 3690
