What's the Least Common Multiple (LCM) of 4 and 48?

Answer

LCM of 4 and 48 is 48

(Forty-eight)

Finding LCM for 4 and 48 using GCF of these numbers

The first method to find LCM for numbers 4 and 48 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:

LCM = (Number1 × Number2) ÷ GCF

GCF of numbers 4 and 48 is 4, so

LCM = (4 × 48) ÷ 4

LCM = 192 ÷ 4

LCM = 48

Finding LCM for 4 and 48 by Listing Multiples

The second method to find LCM for numbers 4 and 48 is to list out the common multiples for both numbers and pick the first one that matches:

Multiples of 4: 4, 8, 12, 16, 20, 24, 28, 32, 36, 40, 44, 48, 52, 56

Multiples of 48: 48, 96, 144

So the LCM for 4 and 48 is 48

Finding LCM for 4 and 48 by Prime Factorization

Another method to find LCM for numbers 4 and 48 is to list all Prime Factors for both numbers and multiply the highest exponent prime factors:

All Prime Factors of 4: 2, 2 (exponent form: 22)

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

24 × 31 = 48
