LCM for 6 and 27
What's the Least Common Multiple (LCM) of 6 and 27?
(Fifty-four)
Finding LCM for 6 and 27 using GCF's of these numbers
The first method to find LCM for numbers 6 and 27 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:
LCM = (Number1 × Number2) ÷ GCF
GCF of numbers 6 and 27 is 3, so
LCM = (6 × 27) ÷ 3
LCM = 162 ÷ 3
LCM = 54
Finding LCM for 6 and 27 by Listing Multiples
The second method to find LCM for numbers 6 and 27 is to list out the common multiples for both nubmers and pick the first which matching:
Multiples of 6: 6, 12, 18, 24, 30, 36, 42, 48, 54, 60, 66
Multiples of 27: 27, 54, 81, 108
So the LCM for 6 and 27 is 54
Finding LCM for 6 and 27 by Prime Factorization
Another method to find LCM for numbers 6 and 27 is to list all Prime Factors for both numbers and multiply the highest exponent prime factors:
All Prime Factors of 6: 2, 3 (exponent form: 21, 31)
All Prime Factors of 27: 3, 3, 3 (exponent form: 33)
21 × 33 = 54
