LCM for 100 and 900
What's the Least Common Multiple (LCM) of 100 and 900?
(Nine hundred)
Finding LCM for 100 and 900 using GCF's of these numbers
The first method to find LCM for numbers 100 and 900 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:
LCM = (Number1 × Number2) ÷ GCF
GCF of numbers 100 and 900 is 100, so
LCM = (100 × 900) ÷ 100
LCM = 90000 ÷ 100
LCM = 900
Finding LCM for 100 and 900 by Listing Multiples
The second method to find LCM for numbers 100 and 900 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 900: 900, 1800, 2700, 3600, 4500, 5400, 6300, 7200, 8100, 9000, 9900, [...], 900
So the LCM for 100 and 900 is 900
Finding LCM for 100 and 900 by Prime Factorization
Another method to find LCM for numbers 100 and 900 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 900: 2, 2, 3, 3, 5, 5 (exponent form: 22, 32, 52)
22 × 52 × 32 = 900
