What's the Least Common Multiple (LCM) of 12 and 80?

Answer

LCM of 12 and 80 is
240

(Two hundred forty)

Finding LCM for 12 and 80 using GCF of these numbers

The first method to find LCM for numbers 12 and 80 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:

LCM = (Number1 × Number2) ÷ GCF

GCF of numbers 12 and 80 is 4, so

LCM = (12 × 80) ÷ 4

LCM = 960 ÷ 4

LCM = 240

Finding LCM for 12 and 80 by Listing Multiples

The second method to find LCM for numbers 12 and 80 is to list out the common multiples for both numbers and pick the first one that matches:

Multiples of 12: 12, 24, 36, 48, 60, 72, 84, 96, 108, 120, 132, 144, 156, 168, 180, 192, 204, 216, 228, 240, 252, 264

Multiples of 80: 80, 160, 240, 320, 400

So the LCM for 12 and 80 is 240

Finding LCM for 12 and 80 by Prime Factorization

Another method to find LCM for numbers 12 and 80 is to list all Prime Factors for both numbers and multiply the highest exponent prime factors:

All Prime Factors of 12: 2, 2, 3 (exponent form: 22, 31)

All Prime Factors of 80: 2, 2, 2, 2, 5 (exponent form: 24, 51)

24 × 31 × 51 = 240
