What's the Least Common Multiple (LCM) of 80 and 205?

Answer

LCM of 80 and 205 is 3,280

(Three thousand, two hundred eighty)

Finding LCM for 80 and 205 using GCF of these numbers

The first method to find LCM for numbers 80 and 205 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:

LCM = (Number1 × Number2) ÷ GCF

GCF of numbers 80 and 205 is 5, so

LCM = (80 × 205) ÷ 5

LCM = 16400 ÷ 5

LCM = 3280

Finding LCM for 80 and 205 by Listing Multiples

The second method to find LCM for numbers 80 and 205 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

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

So the LCM for 80 and 205 is 3280

Finding LCM for 80 and 205 by Prime Factorization

Another method to find LCM for numbers 80 and 205 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 205: 5, 41 (exponent form: 51, 411)

24 × 51 × 411 = 3280
