What's the Least Common Multiple (LCM) of 14 and 28?

Answer

LCM of 14 and 28 is 28

(Twenty-eight)

Finding LCM for 14 and 28 using GCF of these numbers

The first method to find LCM for numbers 14 and 28 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:

LCM = (Number1 × Number2) ÷ GCF

GCF of numbers 14 and 28 is 14, so

LCM = (14 × 28) ÷ 14

LCM = 392 ÷ 14

LCM = 28

Finding LCM for 14 and 28 by Listing Multiples

The second method to find LCM for numbers 14 and 28 is to list out the common multiples for both numbers and pick the first one that matches:

Multiples of 14: 14, 28, 42, 56

Multiples of 28: 28, 56, 84

So the LCM for 14 and 28 is 28

Finding LCM for 14 and 28 by Prime Factorization

Another method to find LCM for numbers 14 and 28 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 28: 2, 2, 7 (exponent form: 22, 71)

22 × 71 = 28
