What's the Least Common Multiple (LCM) of 6 and 23?
(One hundred thirty-eight)
Finding LCM for 6 and 23 using GCF's of these numbers
The first method to find LCM for numbers 6 and 23 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:
LCM = (Number1 × Number2) ÷ GCF
GCF of numbers 6 and 23 is 1, so
LCM = (6 × 23) ÷ 1
LCM = 138 ÷ 1
LCM = 138
Finding LCM for 6 and 23 by Listing Multiples
The second method to find LCM for numbers 6 and 23 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, 72, 78, 84, 90, 96, 102, 108, 114, 120, 126, 132, 138, 144, 150
Multiples of 23: 23, 46, 69, 92, 115, 138, 161, 184
So the LCM for 6 and 23 is 138
Finding LCM for 6 and 23 by Prime Factorization
Another method to find LCM for numbers 6 and 23 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 23: 23 (exponent form: 231)
21 × 31 × 231 = 138
