"Least Common Multiple" Calculator

What's the Least Common Multiple (LCM) of 6 and 81?

Answer

LCM of 6 and 81 is

162

(One hundred sixty-two)

Finding LCM for 6 and 81 using GCF of these numbers

The first method to find LCM for numbers 6 and 81 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:

LCM = (Number1 × Number2) ÷ GCF

GCF of numbers 6 and 81 is 3, so

LCM = (6 × 81) ÷ 3

LCM = 486 ÷ 3

LCM = 162

Finding LCM for 6 and 81 by Listing Multiples

The second method to find LCM for numbers 6 and 81 is to list out the common multiples for both numbers and pick the first one that matches:

Multiples of 6: 6, 12, 18, 24, 30, 36, 42, 48, 54, 60, 66, 72, 78, 84, 90, 96, 102, 108, 114, 120, 126, 132, 138, 144, 150, 156, 162, 168, 174

Multiples of 81: 81, 162, 243, 324

So the LCM for 6 and 81 is 162

Finding LCM for 6 and 81 by Prime Factorization

Another method to find LCM for numbers 6 and 81 is to list all Prime Factors for both numbers and multiply the highest exponent prime factors:

All Prime Factors of 6: 2, 3 (exponent form: 2¹, 3¹)

All Prime Factors of 81: 3, 3, 3, 3 (exponent form: 3⁴)

2¹ × 3⁴ = 162
