What's the Least Common Multiple (LCM) of 3 and 23?

Answer: LCM of 3 and 23 is 69

(Sixty-nine)

Finding LCM for 3 and 23 using GCF's of these numbers

The first method to find LCM for numbers 3 and 23 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:

LCM = (Number1 × Number2) ÷ GCF

GCF of numbers 3 and 23 is 1, so

LCM = (3 × 23) ÷ 1

LCM = 69 ÷ 1

LCM = 69

Finding LCM for 3 and 23 by Listing Multiples

The second method to find LCM for numbers 3 and 23 is to list out the common multiples for both nubmers and pick the first which matching:

Multiples of 3: 3, 6, 9, 12, 15, 18, 21, 24, 27, 30, 33, 36, 39, 42, 45, 48, 51, 54, 57, 60, 63, 66, 69, 72, 75

Multiples of 23: 23, 46, 69, 92, 115

So the LCM for 3 and 23 is 69

Finding LCM for 3 and 23 by Prime Factorization

Another method to find LCM for numbers 3 and 23 is to list all Prime Factors for both numbers and multiply the highest exponent prime factors:

All Prime Factors of 3: 3 (exponent form: 3¹)

All Prime Factors of 23: 23 (exponent form: 23¹)

3¹ × 23¹ = 69
