Answer

LCM of 2 and 23 is 46

(Forty-six)

Finding LCM for 2 and 23 using GCF of these numbers

The first method to find LCM for numbers 2 and 23 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:

LCM = (Number1 × Number2) ÷ GCF

GCF of numbers 2 and 23 is 1, so

LCM = (2 × 23) ÷ 1

LCM = 46 ÷ 1

LCM = 46

Finding LCM for 2 and 23 by Listing Multiples

The second method to find LCM for numbers 2 and 23 is to list out the common multiples for both numbers and pick the first one that matches:

Multiples of 2: 2, 4, 6, 8, 10, 12, 14, 16, 18, 20, 22, 24, 26, 28, 30, 32, 34, 36, 38, 40, 42, 44, 46, 48, 50

Multiples of 23: 23, 46, 69, 92

So the LCM for 2 and 23 is 46

Finding LCM for 2 and 23 by Prime Factorization

Another method to find LCM for numbers 2 and 23 is to list all Prime Factors for both numbers and multiply the highest exponent prime factors:

All Prime Factors of 2: 2 (exponent form: 21)

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

21 × 231 = 46
