What's the Least Common Multiple (LCM) of 80 and 255?

Answer

LCM of 80 and 255 is 4,080

(Four thousand, eighty)

Finding LCM for 80 and 255 using GCF of these numbers

The first method to find LCM for numbers 80 and 255 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:

LCM = (Number1 × Number2) ÷ GCF

GCF of numbers 80 and 255 is 5, so

LCM = (80 × 255) ÷ 5

LCM = 20400 ÷ 5

LCM = 4080

Finding LCM for 80 and 255 by Listing Multiples

The second method to find LCM for numbers 80 and 255 is to list out the common multiples for both numbers and pick the first one that matches:

Multiples of 80: 80, 160, 240, 320, 400, 480, 560, 640, 720, 800, 880, 960, 1040, 1120, 1200, 1280, 1360, 1440, 1520, 1600, 1680, 1760, 1840, 1920, 2000, 2080, 2160, 2240, 2320, 2400, 2480, 2560, 2640, 2720, 2800, 2880, 2960, 3040, 3120, 3200, 3280, 3360, 3440, 3520, 3600, 3680, 3760, 3840, 3920, 4000, 4080, 4160, 4240

Multiples of 255: 255, 510, 765, 1020, 1275, 1530, 1785, 2040, 2295, 2550, 2805, 3060, 3315, 3570, 3825, 4080, 4335, 4590

So the LCM for 80 and 255 is 4080

Finding LCM for 80 and 255 by Prime Factorization

Another method to find LCM for numbers 80 and 255 is to list all Prime Factors for both numbers and multiply the highest exponent prime factors:

All Prime Factors of 80: 2, 2, 2, 2, 5 (exponent form: 24, 51)

All Prime Factors of 255: 3, 5, 17 (exponent form: 31, 51, 171)

24 × 51 × 31 × 171 = 4080
