What's the Least Common Multiple (LCM) of 80 and 490?

Answer

LCM of 80 and 490 is 3,920

(Three thousand, nine hundred twenty)

Finding LCM for 80 and 490 using GCF of these numbers

The first method to find LCM for numbers 80 and 490 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:

LCM = (Number1 × Number2) ÷ GCF

GCF of numbers 80 and 490 is 10, so

LCM = (80 × 490) ÷ 10

LCM = 39200 ÷ 10

LCM = 3920

Finding LCM for 80 and 490 by Listing Multiples

The second method to find LCM for numbers 80 and 490 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

Multiples of 490: 490, 980, 1470, 1960, 2450, 2940, 3430, 3920, 4410, 4900

So the LCM for 80 and 490 is 3920

Finding LCM for 80 and 490 by Prime Factorization

Another method to find LCM for numbers 80 and 490 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 490: 2, 5, 7, 7 (exponent form: 21, 51, 72)

24 × 51 × 72 = 3920
