LCM for 90 and 150
What's the Least Common Multiple (LCM) of 90 and 150?
(Four hundred fifty)
Finding LCM for 90 and 150 using GCF's of these numbers
The first method to find LCM for numbers 90 and 150 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:
LCM = (Number1 × Number2) ÷ GCF
GCF of numbers 90 and 150 is 30, so
LCM = (90 × 150) ÷ 30
LCM = 13500 ÷ 30
LCM = 450
Finding LCM for 90 and 150 by Listing Multiples
The second method to find LCM for numbers 90 and 150 is to list out the common multiples for both nubmers and pick the first which matching:
Multiples of 90: 90, 180, 270, 360, 450, 540, 630
Multiples of 150: 150, 300, 450, 600, 750
So the LCM for 90 and 150 is 450
Finding LCM for 90 and 150 by Prime Factorization
