LCM for 18 and 26
What's the Least Common Multiple (LCM) of 18 and 26?
(Two hundred thirty-four)
Finding LCM for 18 and 26 using GCF's of these numbers
The first method to find LCM for numbers 18 and 26 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:
LCM = (Number1 × Number2) ÷ GCF
GCF of numbers 18 and 26 is 2, so
LCM = (18 × 26) ÷ 2
LCM = 468 ÷ 2
LCM = 234
Finding LCM for 18 and 26 by Listing Multiples
The second method to find LCM for numbers 18 and 26 is to list out the common multiples for both nubmers and pick the first which matching:
Multiples of 18: 18, 36, 54, 72, 90, 108, 126, 144, 162, 180, 198, 216, 234, 252, 270
Multiples of 26: 26, 52, 78, 104, 130, 156, 182, 208, 234, 260, 286
So the LCM for 18 and 26 is 234
Finding LCM for 18 and 26 by Prime Factorization
Another method to find LCM for numbers 18 and 26 is to list all Prime Factors for both numbers and multiply the highest exponent prime factors:
All Prime Factors of 18: 2, 3, 3 (exponent form: 21, 32)
All Prime Factors of 26: 2, 13 (exponent form: 21, 131)
21 × 32 × 131 = 234
