LCM for 14 and 54
What's the Least Common Multiple (LCM) of 14 and 54?
(Three hundred seventy-eight)
Finding LCM for 14 and 54 using GCF's of these numbers
The first method to find LCM for numbers 14 and 54 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:
LCM = (Number1 × Number2) ÷ GCF
GCF of numbers 14 and 54 is 2, so
LCM = (14 × 54) ÷ 2
LCM = 756 ÷ 2
LCM = 378
Finding LCM for 14 and 54 by Listing Multiples
The second method to find LCM for numbers 14 and 54 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, 168, 182, 196, 210, 224, 238, 252, 266, 280, 294, 308, 322, 336, 350, 364, 378, 392, 406
Multiples of 54: 54, 108, 162, 216, 270, 324, 378, 432, 486
So the LCM for 14 and 54 is 378
Finding LCM for 14 and 54 by Prime Factorization
Another method to find LCM for numbers 14 and 54 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 54: 2, 3, 3, 3 (exponent form: 21, 33)
21 × 71 × 33 = 378
