What's the Least Common Multiple (LCM) of 28 and 32?

Answer: LCM of 28 and 32 is 224

(Two hundred twenty-four)

Finding LCM for 28 and 32 using GCF's of these numbers

The first method to find LCM for numbers 28 and 32 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:

LCM = (Number1 × Number2) ÷ GCF

GCF of numbers 28 and 32 is 4, so

LCM = (28 × 32) ÷ 4

LCM = 896 ÷ 4

LCM = 224

Finding LCM for 28 and 32 by Listing Multiples

The second method to find LCM for numbers 28 and 32 is to list out the common multiples for both nubmers and pick the first which matching:

Multiples of 28: 28, 56, 84, 112, 140, 168, 196, 224, 252, 280

Multiples of 32: 32, 64, 96, 128, 160, 192, 224, 256, 288

So the LCM for 28 and 32 is 224

Finding LCM for 28 and 32 by Prime Factorization

Another method to find LCM for numbers 28 and 32 is to list all Prime Factors for both numbers and multiply the highest exponent prime factors:

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

All Prime Factors of 32: 2, 2, 2, 2, 2 (exponent form: 25)

25 × 71 = 224
