What's the Least Common Multiple (LCM) of 12 and 27?

Answer: LCM of 12 and 27 is 108

(One hundred eight)

Finding LCM for 12 and 27 using GCF's of these numbers

The first method to find LCM for numbers 12 and 27 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:

LCM = (Number1 × Number2) ÷ GCF

GCF of numbers 12 and 27 is 3, so

LCM = (12 × 27) ÷ 3

LCM = 324 ÷ 3

LCM = 108

Finding LCM for 12 and 27 by Listing Multiples

The second method to find LCM for numbers 12 and 27 is to list out the common multiples for both nubmers and pick the first which matching:

Multiples of 12: 12, 24, 36, 48, 60, 72, 84, 96, 108, 120, 132

Multiples of 27: 27, 54, 81, 108, 135, 162

So the LCM for 12 and 27 is 108

Finding LCM for 12 and 27 by Prime Factorization

Another method to find LCM for numbers 12 and 27 is to list all Prime Factors for both numbers and multiply the highest exponent prime factors:

All Prime Factors of 12: 2, 2, 3 (exponent form: 2², 3¹)

All Prime Factors of 27: 3, 3, 3 (exponent form: 3³)

2² × 3³ = 108
