What's the Least Common Multiple (LCM) of 48 and 84?

Answer

LCM of 48 and 84 is
336

(Three hundred thirty-six)

Finding LCM for 48 and 84 using GCF of these numbers

The first method to find LCM for numbers 48 and 84 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:

LCM = (Number1 × Number2) ÷ GCF

GCF of numbers 48 and 84 is 12, so

LCM = (48 × 84) ÷ 12

LCM = 4,032 ÷ 12

LCM = 336

Finding LCM for 48 and 84 by Listing Multiples

The second method to find LCM for numbers 48 and 84 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, 288, 336, 384, 432

Multiples of 84: 84, 168, 252, 336, 420, 504

So the LCM for 48 and 84 is 336

Finding LCM for 48 and 84 by Prime Factorization

Another method to find LCM for numbers 48 and 84 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 84: 2, 2, 3, 7 (exponent form: 22, 31, 71)

24 × 31 × 71 = 336
