Least Common Multiple of

and

What's the Least Common Multiple (LCM) of 20 and 225?

Answer

LCM of 20 and 225 is 900

(Nine hundred)

Finding LCM for 20 and 225 using GCF of these numbers

The first method to find LCM for numbers 20 and 225 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:

LCM = (Number1 × Number2) ÷ GCF

GCF of numbers 20 and 225 is 5, so

LCM = (20 × 225) ÷ 5

LCM = 4500 ÷ 5

LCM = 900

Finding LCM for 20 and 225 by Listing Multiples

The second method to find LCM for numbers 20 and 225 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

Multiples of 225: 225, 450, 675, 900, 1125, 1350

So the LCM for 20 and 225 is 900

Finding LCM for 20 and 225 by Prime Factorization

Another method to find LCM for numbers 20 and 225 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 225: 3, 3, 5, 5 (exponent form: 32, 52)

22 × 52 × 32 = 900
