What's the Least Common Multiple (LCM) of 9 and 54?

Answer: LCM of 9 and 54 is 54

(Fifty-four)

Finding LCM for 9 and 54 using GCF's of these numbers

The first method to find LCM for numbers 9 and 54 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:

LCM = (Number1 × Number2) ÷ GCF

GCF of numbers 9 and 54 is 9, so

LCM = (9 × 54) ÷ 9

LCM = 486 ÷ 9

LCM = 54

Finding LCM for 9 and 54 by Listing Multiples

The second method to find LCM for numbers 9 and 54 is to list out the common multiples for both nubmers and pick the first which matching:

Multiples of 9: 9, 18, 27, 36, 45, 54, 63, 72

Multiples of 54: 54, 108, 162, 216, 270, 324, 378, 432, [...], 54

So the LCM for 9 and 54 is 54

Finding LCM for 9 and 54 by Prime Factorization

Another method to find LCM for numbers 9 and 54 is to list all Prime Factors for both numbers and multiply the highest exponent prime factors:

All Prime Factors of 9: 3, 3 (exponent form: 3²)

All Prime Factors of 54: 2, 3, 3, 3 (exponent form: 2¹, 3³)

3³ × 2¹ = 54
