Answer: LCM of 100 and 160 is 800

(Eight hundred)

Finding LCM for 100 and 160 using GCF's of these numbers

The first method to find LCM for numbers 100 and 160 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:

LCM = (Number1 × Number2) ÷ GCF

GCF of numbers 100 and 160 is 20, so

LCM = (100 × 160) ÷ 20

LCM = 16000 ÷ 20

LCM = 800

Finding LCM for 100 and 160 by Listing Multiples

The second method to find LCM for numbers 100 and 160 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

Multiples of 160: 160, 320, 480, 640, 800, 960, 1120

So the LCM for 100 and 160 is 800

Finding LCM for 100 and 160 by Prime Factorization

Another method to find LCM for numbers 100 and 160 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 160: 2, 2, 2, 2, 2, 5 (exponent form: 25, 51)

25 × 52 = 800
