LCM for 100 and 1000
What's the Least Common Multiple (LCM) of 100 and 1000?
(Thousand)
Finding LCM for 100 and 1000 using GCF's of these numbers
The first method to find LCM for numbers 100 and 1000 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:
LCM = (Number1 × Number2) ÷ GCF
GCF of numbers 100 and 1000 is 100, so
LCM = (100 × 1000) ÷ 100
LCM = 100000 ÷ 100
LCM = 1000
Finding LCM for 100 and 1000 by Listing Multiples
The second method to find LCM for numbers 100 and 1000 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, 1200
Multiples of 1000: 1000, 2000, 3000, 4000, 5000, 6000, 7000, 8000, 9000, 10000, 11000, 12000, [...], 1000
So the LCM for 100 and 1000 is 1000
Finding LCM for 100 and 1000 by Prime Factorization
Another method to find LCM for numbers 100 and 1000 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 1000: 2, 2, 2, 5, 5, 5 (exponent form: 23, 53)
23 × 53 = 1000
