What's the Least Common Multiple (LCM) of 18 and 225?

Answer: LCM of 18 and 225 is 450

(Four hundred fifty)

Finding LCM for 18 and 225 using GCF's of these numbers

The first method to find LCM for numbers 18 and 225 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:

LCM = (Number1 × Number2) ÷ GCF

GCF of numbers 18 and 225 is 9, so

LCM = (18 × 225) ÷ 9

LCM = 4050 ÷ 9

LCM = 450

Multiples of 18: 18, 36, 54, 72, 90, 108, 126, 144, 162, 180, 198, 216, 234, 252, 270, 288, 306, 324, 342, 360, 378, 396, 414, 432, 450, 468, 486

Multiples of 225: 225, 450, 675, 900

So the LCM for 18 and 225 is 450

Finding LCM for 18 and 225 by Prime Factorization

Another method to find LCM for numbers 18 and 225 is to list all Prime Factors for both numbers and multiply the highest exponent prime factors:

All Prime Factors of 18: 2, 3, 3 (exponent form: 2¹, 3²)

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

2¹ × 3² × 5² = 450
