LCM for 40 and 150
What's the Least Common Multiple (LCM) of 40 and 150?
(Six hundred)
Finding LCM for 40 and 150 using GCF's of these numbers
The first method to find LCM for numbers 40 and 150 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:
LCM = (Number1 × Number2) ÷ GCF
GCF of numbers 40 and 150 is 10, so
LCM = (40 × 150) ÷ 10
LCM = 6000 ÷ 10
LCM = 600
Finding LCM for 40 and 150 by Listing Multiples
The second method to find LCM for numbers 40 and 150 is to list out the common multiples for both nubmers and pick the first which matching:
Multiples of 40: 40, 80, 120, 160, 200, 240, 280, 320, 360, 400, 440, 480, 520, 560, 600, 640, 680
Multiples of 150: 150, 300, 450, 600, 750, 900
So the LCM for 40 and 150 is 600
Finding LCM for 40 and 150 by Prime Factorization
Another method to find LCM for numbers 40 and 150 is to list all Prime Factors for both numbers and multiply the highest exponent prime factors:
All Prime Factors of 40: 2, 2, 2, 5 (exponent form: 23, 51)
All Prime Factors of 150: 2, 3, 5, 5 (exponent form: 21, 31, 52)
23 × 52 × 31 = 600
