What's the Least Common Multiple (LCM) of 72 and 96?

Answer

LCM of 72 and 96 is
288

(Two hundred eighty-eight)

Finding LCM for 72 and 96 using GCF of these numbers

The first method to find LCM for numbers 72 and 96 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:

LCM = (Number1 × Number2) ÷ GCF

GCF of numbers 72 and 96 is 24, so

LCM = (72 × 96) ÷ 24

LCM = 6,912 ÷ 24

LCM = 288

Finding LCM for 72 and 96 by Listing Multiples

The second method to find LCM for numbers 72 and 96 is to list out the common multiples for both numbers and pick the first one that matches:

Multiples of 72: 72, 144, 216, 288, 360, 432

Multiples of 96: 96, 192, 288, 384, 480

So the LCM for 72 and 96 is 288

Finding LCM for 72 and 96 by Prime Factorization

Another method to find LCM for numbers 72 and 96 is to list all Prime Factors for both numbers and multiply the highest exponent prime factors:

All Prime Factors of 72: 2, 2, 2, 3, 3 (exponent form: 23, 32)

All Prime Factors of 96: 2, 2, 2, 2, 2, 3 (exponent form: 25, 31)

25 × 32 = 288
