LCM for 270 and 450
What's the Least Common Multiple (LCM) of 270 and 450?
Answer
(One thousand three hundred fifty)
Finding LCM for 270 and 450 using GCF of these numbers
The first method to find LCM for numbers 270 and 450 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:
LCM = (Number1 × Number2) ÷ GCF
GCF of numbers 270 and 450 is 90, so
LCM = (270 × 450) ÷ 90
LCM = 121,500 ÷ 90
LCM = 1,350
Finding LCM for 270 and 450 by Listing Multiples
The second method to find LCM for numbers 270 and 450 is to list out the common multiples for both numbers and pick the first one that matches:
Multiples of 270: 270, 540, 810, 1,080, 1,350, 1,620, 1,890
Multiples of 450: 450, 900, 1,350, 1,800, 2,250
So the LCM for 270 and 450 is 1,350
Finding LCM for 270 and 450 by Prime Factorization
Another method to find LCM for numbers 270 and 450 is to list all Prime Factors for both numbers and multiply the highest exponent prime factors:
All Prime Factors of 270: 2, 3, 3, 3, 5 (exponent form: 21, 33, 51)
All Prime Factors of 450: 2, 3, 3, 5, 5 (exponent form: 21, 32, 52)
21 × 33 × 52 = 1,350
