What's the Least Common Multiple (LCM) of 40 and 180?

Answer

LCM of 40 and 180 is 360

(Three hundred sixty)

Finding LCM for 40 and 180 using GCF of these numbers

The first method to find LCM for numbers 40 and 180 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:

LCM = (Number1 × Number2) ÷ GCF

GCF of numbers 40 and 180 is 20, so

LCM = (40 × 180) ÷ 20

LCM = 7200 ÷ 20

LCM = 360

Finding LCM for 40 and 180 by Listing Multiples

The second method to find LCM for numbers 40 and 180 is to list out the common multiples for both numbers and pick the first one that matches:

Multiples of 40: 40, 80, 120, 160, 200, 240, 280, 320, 360, 400, 440

Multiples of 180: 180, 360, 540, 720

So the LCM for 40 and 180 is 360

Finding LCM for 40 and 180 by Prime Factorization

Another method to find LCM for numbers 40 and 180 is to list all Prime Factors for both numbers and multiply the highest exponent prime factors:

All Prime Factors of 40: 2, 2, 2, 5 (exponent form: 23, 51)

All Prime Factors of 180: 2, 2, 3, 3, 5 (exponent form: 22, 32, 51)

23 × 51 × 32 = 360
