Answer

LCM of 48 and 120 is 240

(Two hundred forty)

Finding LCM for 48 and 120 using GCF of these numbers

The first method to find LCM for numbers 48 and 120 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:

LCM = (Number1 × Number2) ÷ GCF

GCF of numbers 48 and 120 is 24, so

LCM = (48 × 120) ÷ 24

LCM = 5760 ÷ 24

LCM = 240

Finding LCM for 48 and 120 by Listing Multiples

The second method to find LCM for numbers 48 and 120 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

Multiples of 120: 120, 240, 360, 480

So the LCM for 48 and 120 is 240

Finding LCM for 48 and 120 by Prime Factorization

Another method to find LCM for numbers 48 and 120 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 120: 2, 2, 2, 3, 5 (exponent form: 23, 31, 51)

24 × 31 × 51 = 240
