Answer: LCM of 80 and 200 is 400

(Four hundred)

Finding LCM for 80 and 200 using GCF's of these numbers

The first method to find LCM for numbers 80 and 200 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:

LCM = (Number1 × Number2) ÷ GCF

GCF of numbers 80 and 200 is 40, so

LCM = (80 × 200) ÷ 40

LCM = 16000 ÷ 40

LCM = 400

Finding LCM for 80 and 200 by Listing Multiples

The second method to find LCM for numbers 80 and 200 is to list out the common multiples for both nubmers and pick the first which matching:

Multiples of 80: 80, 160, 240, 320, 400, 480, 560

Multiples of 200: 200, 400, 600, 800

So the LCM for 80 and 200 is 400

Finding LCM for 80 and 200 by Prime Factorization

Another method to find LCM for numbers 80 and 200 is to list all Prime Factors for both numbers and multiply the highest exponent prime factors:

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

All Prime Factors of 200: 2, 2, 2, 5, 5 (exponent form: 23, 52)

24 × 52 = 400
