What's the Least Common Multiple (LCM) of 80 and 155?

Answer

LCM of 80 and 155 is 2,480

(Two thousand, four hundred eighty)

Finding LCM for 80 and 155 using GCF of these numbers

The first method to find LCM for numbers 80 and 155 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:

LCM = (Number1 × Number2) ÷ GCF

GCF of numbers 80 and 155 is 5, so

LCM = (80 × 155) ÷ 5

LCM = 12400 ÷ 5

LCM = 2480

Finding LCM for 80 and 155 by Listing Multiples

The second method to find LCM for numbers 80 and 155 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

Multiples of 155: 155, 310, 465, 620, 775, 930, 1085, 1240, 1395, 1550, 1705, 1860, 2015, 2170, 2325, 2480, 2635, 2790

So the LCM for 80 and 155 is 2480

Finding LCM for 80 and 155 by Prime Factorization

Another method to find LCM for numbers 80 and 155 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 155: 5, 31 (exponent form: 51, 311)

24 × 51 × 311 = 2480
