What's the Least Common Multiple (LCM) of 90 and 255?

Answer

LCM of 90 and 255 is 1,530

(One thousand, five hundred thirty)

Finding LCM for 90 and 255 using GCF of these numbers

The first method to find LCM for numbers 90 and 255 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:

LCM = (Number1 × Number2) ÷ GCF

GCF of numbers 90 and 255 is 15, so

LCM = (90 × 255) ÷ 15

LCM = 22950 ÷ 15

LCM = 1530

Finding LCM for 90 and 255 by Listing Multiples

The second method to find LCM for numbers 90 and 255 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

Multiples of 255: 255, 510, 765, 1020, 1275, 1530, 1785, 2040

So the LCM for 90 and 255 is 1530

Finding LCM for 90 and 255 by Prime Factorization

Another method to find LCM for numbers 90 and 255 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 255: 3, 5, 17 (exponent form: 31, 51, 171)

21 × 32 × 51 × 171 = 1530
