LCM for 18 and 32

What's the Least Common Multiple (LCM) of 18 and 32?

Answer: LCM of 18 and 32 is 288

(Two hundred eighty-eight)

Finding LCM for 18 and 32 using GCF's of these numbers

The first method to find LCM for numbers 18 and 32 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:

LCM = (Number1 × Number2) ÷ GCF

GCF of numbers 18 and 32 is 2, so

LCM = (18 × 32) ÷ 2

LCM = 576 ÷ 2

LCM = 288

Finding LCM for 18 and 32 by Listing Multiples

The second method to find LCM for numbers 18 and 32 is to list out the common multiples for both nubmers and pick the first which matching:

Multiples of 18: 18, 36, 54, 72, 90, 108, 126, 144, 162, 180, 198, 216, 234, 252, 270, 288, 306, 324

Multiples of 32: 32, 64, 96, 128, 160, 192, 224, 256, 288, 320, 352

So the LCM for 18 and 32 is 288

Finding LCM for 18 and 32 by Prime Factorization

Another method to find LCM for numbers 18 and 32 is to list all Prime Factors for both numbers and multiply the highest exponent prime factors:

All Prime Factors of 18: 2, 3, 3 (exponent form: 21, 32)

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

25 × 32 = 288
