LCM for 14 and 9
What's the Least Common Multiple (LCM) of 14 and 9?
(One hundred twenty-six)
Finding LCM for 14 and 9 using GCF's of these numbers
The first method to find LCM for numbers 14 and 9 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:
LCM = (Number1 × Number2) ÷ GCF
GCF of numbers 14 and 9 is 1, so
LCM = (14 × 9) ÷ 1
LCM = 126 ÷ 1
LCM = 126
Finding LCM for 14 and 9 by Listing Multiples
The second method to find LCM for numbers 14 and 9 is to list out the common multiples for both nubmers and pick the first which matching:
Multiples of 14: 14, 28, 42, 56, 70, 84, 98, 112, 126, 140, 154
Multiples of 9: 9, 18, 27, 36, 45, 54, 63, 72, 81, 90, 99, 108, 117, 126, 135, 144
So the LCM for 14 and 9 is 126
Finding LCM for 14 and 9 by Prime Factorization
Another method to find LCM for numbers 14 and 9 is to list all Prime Factors for both numbers and multiply the highest exponent prime factors:
All Prime Factors of 14: 2, 7 (exponent form: 21, 71)
All Prime Factors of 9: 3, 3 (exponent form: 32)
21 × 71 × 32 = 126
