"Least Common Multiple" Calculator

What's the Least Common Multiple (LCM) of 16 and 18?

Answer

LCM of 16 and 18 is

144

(One hundred forty-four)

Finding LCM for 16 and 18 using GCF of these numbers

The first method to find LCM for numbers 16 and 18 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:

LCM = (Number1 × Number2) ÷ GCF

GCF of numbers 16 and 18 is 2, so

LCM = (16 × 18) ÷ 2

LCM = 288 ÷ 2

LCM = 144

Finding LCM for 16 and 18 by Listing Multiples

The second method to find LCM for numbers 16 and 18 is to list out the common multiples for both numbers and pick the first one that matches:

Multiples of 16: 16, 32, 48, 64, 80, 96, 112, 128, 144, 160, 176

Multiples of 18: 18, 36, 54, 72, 90, 108, 126, 144, 162, 180

So the LCM for 16 and 18 is 144

Finding LCM for 16 and 18 by Prime Factorization

Another method to find LCM for numbers 16 and 18 is to list all Prime Factors for both numbers and multiply the highest exponent prime factors:

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

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

2⁴ × 3² = 144
