LCM for 18 and 14

What's the Least Common Multiple (LCM) of 18 and 14?

Answer: LCM of 18 and 14 is 126

(One hundred twenty-six)

Finding LCM for 18 and 14 using GCF's of these numbers

The first method to find LCM for numbers 18 and 14 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:

LCM = (Number1 × Number2) ÷ GCF

GCF of numbers 18 and 14 is 2, so

LCM = (18 × 14) ÷ 2

LCM = 252 ÷ 2

LCM = 126

Finding LCM for 18 and 14 by Listing Multiples

The second method to find LCM for numbers 18 and 14 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

Multiples of 14: 14, 28, 42, 56, 70, 84, 98, 112, 126, 140, 154

So the LCM for 18 and 14 is 126

Finding LCM for 18 and 14 by Prime Factorization

Another method to find LCM for numbers 18 and 14 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 14: 2, 7 (exponent form: 21, 71)

21 × 32 × 71 = 126
