Answer: LCM of 24 and 28 is 168

(One hundred sixty-eight)

Finding LCM for 24 and 28 using GCF's of these numbers

The first method to find LCM for numbers 24 and 28 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:

LCM = (Number1 × Number2) ÷ GCF

GCF of numbers 24 and 28 is 4, so

LCM = (24 × 28) ÷ 4

LCM = 672 ÷ 4

LCM = 168

Finding LCM for 24 and 28 by Listing Multiples

The second method to find LCM for numbers 24 and 28 is to list out the common multiples for both nubmers and pick the first which matching:

Multiples of 24: 24, 48, 72, 96, 120, 144, 168, 192, 216

Multiples of 28: 28, 56, 84, 112, 140, 168, 196, 224

So the LCM for 24 and 28 is 168

Finding LCM for 24 and 28 by Prime Factorization

Another method to find LCM for numbers 24 and 28 is to list all Prime Factors for both numbers and multiply the highest exponent prime factors:

All Prime Factors of 24: 2, 2, 2, 3 (exponent form: 23, 31)

All Prime Factors of 28: 2, 2, 7 (exponent form: 22, 71)

23 × 31 × 71 = 168
