LCM for 2 and 50
What's the Least Common Multiple (LCM) of 2 and 50?
(Fifty)
Finding LCM for 2 and 50 using GCF's of these numbers
The first method to find LCM for numbers 2 and 50 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:
LCM = (Number1 × Number2) ÷ GCF
GCF of numbers 2 and 50 is 2, so
LCM = (2 × 50) ÷ 2
LCM = 100 ÷ 2
LCM = 50
Finding LCM for 2 and 50 by Listing Multiples
The second method to find LCM for numbers 2 and 50 is to list out the common multiples for both nubmers and pick the first which matching:
Multiples of 2: 2, 4, 6, 8, 10, 12, 14, 16, 18, 20, 22, 24, 26, 28, 30, 32, 34, 36, 38, 40, 42, 44, 46, 48, 50, 52, 54
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, [...], 50
So the LCM for 2 and 50 is 50
Finding LCM for 2 and 50 by Prime Factorization
Another method to find LCM for numbers 2 and 50 is to list all Prime Factors for both numbers and multiply the highest exponent prime factors:
All Prime Factors of 2: 2 (exponent form: 21)
All Prime Factors of 50: 2, 5, 5 (exponent form: 21, 52)
21 × 52 = 50
