LCM for 2 and 16

What's the Least Common Multiple (LCM) of 2 and 16?

Answer: LCM of 2 and 16 is 16

(Sixteen)

Finding LCM for 2 and 16 using GCF's of these numbers

The first method to find LCM for numbers 2 and 16 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:

LCM = (Number1 × Number2) ÷ GCF

GCF of numbers 2 and 16 is 2, so

LCM = (2 × 16) ÷ 2

LCM = 32 ÷ 2

LCM = 16

Finding LCM for 2 and 16 by Listing Multiples

The second method to find LCM for numbers 2 and 16 is to list out the common multiples for both nubmers and pick the first which matching:

Multiples of 2: 2, 4, 6, 8, 10, 12, 14, 16, 18, 20

Multiples of 16: 16, 32, 48, 64, 80, 96, 112, 128, 144, 160, [...], 16

So the LCM for 2 and 16 is 16

Finding LCM for 2 and 16 by Prime Factorization

Another method to find LCM for numbers 2 and 16 is to list all Prime Factors for both numbers and multiply the highest exponent prime factors:

All Prime Factors of 2: 2 (exponent form: 21)

All Prime Factors of 16: 2, 2, 2, 2 (exponent form: 24)

24 = 16
