LCM for 3 and 14
What's the Least Common Multiple (LCM) of 3 and 14?
(Forty-two)
Finding LCM for 3 and 14 using GCF's of these numbers
The first method to find LCM for numbers 3 and 14 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:
LCM = (Number1 × Number2) ÷ GCF
GCF of numbers 3 and 14 is 1, so
LCM = (3 × 14) ÷ 1
LCM = 42 ÷ 1
LCM = 42
Finding LCM for 3 and 14 by Listing Multiples
The second method to find LCM for numbers 3 and 14 is to list out the common multiples for both nubmers and pick the first which matching:
Multiples of 3: 3, 6, 9, 12, 15, 18, 21, 24, 27, 30, 33, 36, 39, 42, 45, 48
Multiples of 14: 14, 28, 42, 56, 70
So the LCM for 3 and 14 is 42
Finding LCM for 3 and 14 by Prime Factorization
Another method to find LCM for numbers 3 and 14 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 14: 2, 7 (exponent form: 21, 71)
31 × 21 × 71 = 42
