LCM for 70 and 150
What's the Least Common Multiple (LCM) of 70 and 150?
(One thousand, fifty)
Finding LCM for 70 and 150 using GCF's of these numbers
The first method to find LCM for numbers 70 and 150 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:
LCM = (Number1 × Number2) ÷ GCF
GCF of numbers 70 and 150 is 10, so
LCM = (70 × 150) ÷ 10
LCM = 10500 ÷ 10
LCM = 1050
Finding LCM for 70 and 150 by Listing Multiples
The second method to find LCM for numbers 70 and 150 is to list out the common multiples for both nubmers and pick the first which matching:
Multiples of 70: 70, 140, 210, 280, 350, 420, 490, 560, 630, 700, 770, 840, 910, 980, 1050, 1120, 1190
Multiples of 150: 150, 300, 450, 600, 750, 900, 1050, 1200, 1350
So the LCM for 70 and 150 is 1050
Finding LCM for 70 and 150 by Prime Factorization
Another method to find LCM for numbers 70 and 150 is to list all Prime Factors for both numbers and multiply the highest exponent prime factors:
All Prime Factors of 70: 2, 5, 7 (exponent form: 21, 51, 71)
All Prime Factors of 150: 2, 3, 5, 5 (exponent form: 21, 31, 52)
21 × 52 × 71 × 31 = 1050
