LCM for 50 and 245
What's the Least Common Multiple (LCM) of 50 and 245?
Answer
(Two thousand, four hundred fifty)
Finding LCM for 50 and 245 using GCF of these numbers
The first method to find LCM for numbers 50 and 245 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:
LCM = (Number1 × Number2) ÷ GCF
GCF of numbers 50 and 245 is 5, so
LCM = (50 × 245) ÷ 5
LCM = 12250 ÷ 5
LCM = 2450
Finding LCM for 50 and 245 by Listing Multiples
The second method to find LCM for numbers 50 and 245 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, 2100, 2150, 2200, 2250, 2300, 2350, 2400, 2450, 2500, 2550
Multiples of 245: 245, 490, 735, 980, 1225, 1470, 1715, 1960, 2205, 2450, 2695, 2940
So the LCM for 50 and 245 is 2450
Finding LCM for 50 and 245 by Prime Factorization
Another method to find LCM for numbers 50 and 245 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 245: 5, 7, 7 (exponent form: 51, 72)
21 × 52 × 72 = 2450
