What's the Least Common Multiple (LCM) of 90 and 285?

Answer

LCM of 90 and 285 is 1,710

(One thousand, seven hundred ten)

Finding LCM for 90 and 285 using GCF of these numbers

The first method to find LCM for numbers 90 and 285 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:

LCM = (Number1 × Number2) ÷ GCF

GCF of numbers 90 and 285 is 15, so

LCM = (90 × 285) ÷ 15

LCM = 25650 ÷ 15

LCM = 1710

Finding LCM for 90 and 285 by Listing Multiples

The second method to find LCM for numbers 90 and 285 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

Multiples of 285: 285, 570, 855, 1140, 1425, 1710, 1995, 2280

So the LCM for 90 and 285 is 1710

Finding LCM for 90 and 285 by Prime Factorization

Another method to find LCM for numbers 90 and 285 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 285: 3, 5, 19 (exponent form: 31, 51, 191)

21 × 32 × 51 × 191 = 1710
