LCM for 3 and 16
What's the Least Common Multiple (LCM) of 3 and 16?
(Forty-eight)
Finding LCM for 3 and 16 using GCF's of these numbers
The first method to find LCM for numbers 3 and 16 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:
LCM = (Number1 × Number2) ÷ GCF
GCF of numbers 3 and 16 is 1, so
LCM = (3 × 16) ÷ 1
LCM = 48 ÷ 1
LCM = 48
Finding LCM for 3 and 16 by Listing Multiples
The second method to find LCM for numbers 3 and 16 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, 51, 54
Multiples of 16: 16, 32, 48, 64, 80
So the LCM for 3 and 16 is 48
Finding LCM for 3 and 16 by Prime Factorization
Another method to find LCM for numbers 3 and 16 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 16: 2, 2, 2, 2 (exponent form: 24)
31 × 24 = 48
