LCM for 12 and 16

What's the Least Common Multiple (LCM) of 12 and 16?

Answer: LCM of 12 and 16 is 48

(Forty-eight)

Finding LCM for 12 and 16 using GCF's of these numbers

The first method to find LCM for numbers 12 and 16 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:

LCM = (Number1 × Number2) ÷ GCF

GCF of numbers 12 and 16 is 4, so

LCM = (12 × 16) ÷ 4

LCM = 192 ÷ 4

LCM = 48

Finding LCM for 12 and 16 by Listing Multiples

The second method to find LCM for numbers 12 and 16 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

Multiples of 16: 16, 32, 48, 64, 80

So the LCM for 12 and 16 is 48

Finding LCM for 12 and 16 by Prime Factorization

Another method to find LCM for numbers 12 and 16 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 16: 2, 2, 2, 2 (exponent form: 24)

24 × 31 = 48
