What's the Least Common Multiple (LCM) of 20 and 48?

Answer: LCM of 20 and 48 is 240

(Two hundred forty)

Finding LCM for 20 and 48 using GCF's of these numbers

The first method to find LCM for numbers 20 and 48 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:

LCM = (Number1 × Number2) ÷ GCF

GCF of numbers 20 and 48 is 4, so

LCM = (20 × 48) ÷ 4

LCM = 960 ÷ 4

LCM = 240

Finding LCM for 20 and 48 by Listing Multiples

The second method to find LCM for numbers 20 and 48 is to list out the common multiples for both nubmers and pick the first which matching:

Multiples of 20: 20, 40, 60, 80, 100, 120, 140, 160, 180, 200, 220, 240, 260, 280

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

So the LCM for 20 and 48 is 240

Finding LCM for 20 and 48 by Prime Factorization

Another method to find LCM for numbers 20 and 48 is to list all Prime Factors for both numbers and multiply the highest exponent prime factors:

All Prime Factors of 20: 2, 2, 5 (exponent form: 22, 51)

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

24 × 51 × 31 = 240
