What's the Least Common Multiple (LCM) of 48 and 56?

Answer: LCM of 48 and 56 is 336

(Three hundred thirty-six)

Finding LCM for 48 and 56 using GCF's of these numbers

The first method to find LCM for numbers 48 and 56 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:

LCM = (Number1 × Number2) ÷ GCF

GCF of numbers 48 and 56 is 8, so

LCM = (48 × 56) ÷ 8

LCM = 2688 ÷ 8

LCM = 336

Finding LCM for 48 and 56 by Listing Multiples

The second method to find LCM for numbers 48 and 56 is to list out the common multiples for both nubmers and pick the first which matching:

Multiples of 48: 48, 96, 144, 192, 240, 288, 336, 384, 432

Multiples of 56: 56, 112, 168, 224, 280, 336, 392, 448

So the LCM for 48 and 56 is 336

Finding LCM for 48 and 56 by Prime Factorization

Another method to find LCM for numbers 48 and 56 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 56: 2, 2, 2, 7 (exponent form: 2³, 7¹)

2⁴ × 3¹ × 7¹ = 336
