Answer: LCM of 100 and 180 is 900

(Nine hundred)

Finding LCM for 100 and 180 using GCF's of these numbers

The first method to find LCM for numbers 100 and 180 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:

LCM = (Number1 × Number2) ÷ GCF

GCF of numbers 100 and 180 is 20, so

LCM = (100 × 180) ÷ 20

LCM = 18000 ÷ 20

LCM = 900

Finding LCM for 100 and 180 by Listing Multiples

The second method to find LCM for numbers 100 and 180 is to list out the common multiples for both nubmers and pick the first which matching:

Multiples of 100: 100, 200, 300, 400, 500, 600, 700, 800, 900, 1000, 1100

Multiples of 180: 180, 360, 540, 720, 900, 1080, 1260

So the LCM for 100 and 180 is 900

Finding LCM for 100 and 180 by Prime Factorization

Another method to find LCM for numbers 100 and 180 is to list all Prime Factors for both numbers and multiply the highest exponent prime factors:

All Prime Factors of 100: 2, 2, 5, 5 (exponent form: 22, 52)

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

22 × 52 × 32 = 900
