What's the Least Common Multiple (LCM) of 20 and 275?

Answer

LCM of 20 and 275 is 1,100

(One thousand, one hundred)

Finding LCM for 20 and 275 using GCF of these numbers

The first method to find LCM for numbers 20 and 275 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:

LCM = (Number1 × Number2) ÷ GCF

GCF of numbers 20 and 275 is 5, so

LCM = (20 × 275) ÷ 5

LCM = 5500 ÷ 5

LCM = 1100

Finding LCM for 20 and 275 by Listing Multiples

The second method to find LCM for numbers 20 and 275 is to list out the common multiples for both numbers and pick the first one that matches:

Multiples of 20: 20, 40, 60, 80, 100, 120, 140, 160, 180, 200, 220, 240, 260, 280, 300, 320, 340, 360, 380, 400, 420, 440, 460, 480, 500, 520, 540, 560, 580, 600, 620, 640, 660, 680, 700, 720, 740, 760, 780, 800, 820, 840, 860, 880, 900, 920, 940, 960, 980, 1000, 1020, 1040, 1060, 1080, 1100, 1120, 1140

Multiples of 275: 275, 550, 825, 1100, 1375, 1650

So the LCM for 20 and 275 is 1100

Finding LCM for 20 and 275 by Prime Factorization

Another method to find LCM for numbers 20 and 275 is to list all Prime Factors for both numbers and multiply the highest exponent prime factors:

All Prime Factors of 20: 2, 2, 5 (exponent form: 22, 51)

All Prime Factors of 275: 5, 5, 11 (exponent form: 52, 111)

22 × 52 × 111 = 1100
