LCM for 6 and 40

"Least Common Multiple" Calculator

What's the Least Common Multiple (LCM) of 6 and 40?

Answer

LCM of 6 and 40 is

120

(One hundred twenty)

Finding LCM for 6 and 40 using GCF of these numbers

The first method to find LCM for numbers 6 and 40 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:

LCM = (Number1 × Number2) ÷ GCF

GCF of numbers 6 and 40 is 2, so

LCM = (6 × 40) ÷ 2

LCM = 240 ÷ 2

LCM = 120

Finding LCM for 6 and 40 by Listing Multiples

The second method to find LCM for numbers 6 and 40 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

Multiples of 40: 40, 80, 120, 160, 200

So the LCM for 6 and 40 is 120

Finding LCM for 6 and 40 by Prime Factorization

Another method to find LCM for numbers 6 and 40 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 40: 2, 2, 2, 5 (exponent form: 2³, 5¹)

2³ × 3¹ × 5¹ = 120
