"Least Common Multiple" Calculator
What's the Least Common Multiple (LCM) of 3 and 2?
Answer: LCM of 3 and 2 is 6
(Six)
Finding LCM for 3 and 2 using GCF's of these numbers
The first method to find LCM for numbers 3 and 2 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:
LCM = (Number1 × Number2) ÷ GCF
GCF of numbers 3 and 2 is 1, so
LCM = (3 × 2) ÷ 1
LCM = 6 ÷ 1
LCM = 6
Finding LCM for 3 and 2 by Listing Multiples
The second method to find LCM for numbers 3 and 2 is to list out the common multiples for both nubmers and pick the first which matching:
Multiples of 3: 3, 6, 9, 12
Multiples of 2: 2, 4, 6, 8, 10
So the LCM for 3 and 2 is 6
Finding LCM for 3 and 2 by Prime Factorization
Another method to find LCM for numbers 3 and 2 is to list all Prime Factors for both numbers and multiply the highest exponent prime factors:
All Prime Factors of 3: 3 (exponent form: 31)
All Prime Factors of 2: 2 (exponent form: 21)
31 × 21 = 6
