What's the Least Common Multiple (LCM) of 40 and 225?

Answer

LCM of 40 and 225 is 1,800

(One thousand, eight hundred)

Finding LCM for 40 and 225 using GCF of these numbers

The first method to find LCM for numbers 40 and 225 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:

LCM = (Number1 × Number2) ÷ GCF

GCF of numbers 40 and 225 is 5, so

LCM = (40 × 225) ÷ 5

LCM = 9000 ÷ 5

LCM = 1800

Finding LCM for 40 and 225 by Listing Multiples

The second method to find LCM for numbers 40 and 225 is to list out the common multiples for both numbers and pick the first one that matches:

Multiples of 40: 40, 80, 120, 160, 200, 240, 280, 320, 360, 400, 440, 480, 520, 560, 600, 640, 680, 720, 760, 800, 840, 880, 920, 960, 1000, 1040, 1080, 1120, 1160, 1200, 1240, 1280, 1320, 1360, 1400, 1440, 1480, 1520, 1560, 1600, 1640, 1680, 1720, 1760, 1800, 1840, 1880

Multiples of 225: 225, 450, 675, 900, 1125, 1350, 1575, 1800, 2025, 2250

So the LCM for 40 and 225 is 1800

Finding LCM for 40 and 225 by Prime Factorization

Another method to find LCM for numbers 40 and 225 is to list all Prime Factors for both numbers and multiply the highest exponent prime factors:

All Prime Factors of 40: 2, 2, 2, 5 (exponent form: 23, 51)

All Prime Factors of 225: 3, 3, 5, 5 (exponent form: 32, 52)

23 × 52 × 32 = 1800
