LCM for 50 and 390
What's the Least Common Multiple (LCM) of 50 and 390?
Answer
(One thousand, nine hundred fifty)
Finding LCM for 50 and 390 using GCF of these numbers
The first method to find LCM for numbers 50 and 390 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:
LCM = (Number1 × Number2) ÷ GCF
GCF of numbers 50 and 390 is 10, so
LCM = (50 × 390) ÷ 10
LCM = 19500 ÷ 10
LCM = 1950
Finding LCM for 50 and 390 by Listing Multiples
The second method to find LCM for numbers 50 and 390 is to list out the common multiples for both numbers and pick the first one that matches:
Multiples of 50: 50, 100, 150, 200, 250, 300, 350, 400, 450, 500, 550, 600, 650, 700, 750, 800, 850, 900, 950, 1000, 1050, 1100, 1150, 1200, 1250, 1300, 1350, 1400, 1450, 1500, 1550, 1600, 1650, 1700, 1750, 1800, 1850, 1900, 1950, 2000, 2050
Multiples of 390: 390, 780, 1170, 1560, 1950, 2340, 2730
So the LCM for 50 and 390 is 1950
Finding LCM for 50 and 390 by Prime Factorization
Another method to find LCM for numbers 50 and 390 is to list all Prime Factors for both numbers and multiply the highest exponent prime factors:
All Prime Factors of 50: 2, 5, 5 (exponent form: 21, 52)
All Prime Factors of 390: 2, 3, 5, 13 (exponent form: 21, 31, 51, 131)
21 × 52 × 31 × 131 = 1950
