Answer: LCM of 30 and 255 is 510

(Five hundred ten)

Finding LCM for 30 and 255 using GCF's of these numbers

The first method to find LCM for numbers 30 and 255 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:

LCM = (Number1 × Number2) ÷ GCF

GCF of numbers 30 and 255 is 15, so

LCM = (30 × 255) ÷ 15

LCM = 7650 ÷ 15

LCM = 510

Finding LCM for 30 and 255 by Listing Multiples

The second method to find LCM for numbers 30 and 255 is to list out the common multiples for both nubmers and pick the first which matching:

Multiples of 30: 30, 60, 90, 120, 150, 180, 210, 240, 270, 300, 330, 360, 390, 420, 450, 480, 510, 540, 570

Multiples of 255: 255, 510, 765, 1020

So the LCM for 30 and 255 is 510
