What's the Least Common Multiple (LCM) of 48 and 72?

Answer

LCM of 48 and 72 is
144

(One hundred forty-four)

Finding LCM for 48 and 72 using GCF of these numbers

The first method to find LCM for numbers 48 and 72 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:

LCM = (Number1 × Number2) ÷ GCF

GCF of numbers 48 and 72 is 24, so

LCM = (48 × 72) ÷ 24

LCM = 3,456 ÷ 24

LCM = 144

Finding LCM for 48 and 72 by Listing Multiples

The second method to find LCM for numbers 48 and 72 is to list out the common multiples for both numbers and pick the first one that matches:

Multiples of 48: 48, 96, 144, 192, 240

Multiples of 72: 72, 144, 216, 288

So the LCM for 48 and 72 is 144

Finding LCM for 48 and 72 by Prime Factorization

Another method to find LCM for numbers 48 and 72 is to list all Prime Factors for both numbers and multiply the highest exponent prime factors:

All Prime Factors of 48: 2, 2, 2, 2, 3 (exponent form: 24, 31)

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

24 × 32 = 144
