"Least Common Multiple" Calculator
What's the Least Common Multiple (LCM) of 23 and 46?
Answer
LCM of 23 and 46 is 46
(Forty-six)
Finding LCM for 23 and 46 using GCF of these numbers
The first method to find LCM for numbers 23 and 46 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:
LCM = (Number1 × Number2) ÷ GCF
GCF of numbers 23 and 46 is 23, so
LCM = (23 × 46) ÷ 23
LCM = 1058 ÷ 23
LCM = 46
Finding LCM for 23 and 46 by Listing Multiples
The second method to find LCM for numbers 23 and 46 is to list out the common multiples for both numbers and pick the first one that matches:
Multiples of 23: 23, 46, 69, 92
Multiples of 46: 46, 92, 138
So the LCM for 23 and 46 is 46
Finding LCM for 23 and 46 by Prime Factorization
Another method to find LCM for numbers 23 and 46 is to list all Prime Factors for both numbers and multiply the highest exponent prime factors:
All Prime Factors of 23: 23 (exponent form: 231)
All Prime Factors of 46: 2, 23 (exponent form: 21, 231)
231 × 21 = 46
