What's the Least Common Multiple (LCM) of 32 and 80?

Answer

LCM of 32 and 80 is
160

(One hundred sixty)

Finding LCM for 32 and 80 using GCF of these numbers

The first method to find LCM for numbers 32 and 80 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:

LCM = (Number1 × Number2) ÷ GCF

GCF of numbers 32 and 80 is 16, so

LCM = (32 × 80) ÷ 16

LCM = 2,560 ÷ 16

LCM = 160

Finding LCM for 32 and 80 by Listing Multiples

The second method to find LCM for numbers 32 and 80 is to list out the common multiples for both numbers and pick the first one that matches:

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

Multiples of 80: 80, 160, 240, 320

So the LCM for 32 and 80 is 160

Finding LCM for 32 and 80 by Prime Factorization

Another method to find LCM for numbers 32 and 80 is to list all Prime Factors for both numbers and multiply the highest exponent prime factors:

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

All Prime Factors of 80: 2, 2, 2, 2, 5 (exponent form: 24, 51)

25 × 51 = 160
