least common multiple for 4 and 8
Understand the Problem
The question is asking for the least common multiple (LCM) of the numbers 4 and 8, which is the smallest number that is a multiple of both. To solve this, we will identify the multiples of each number and find the smallest common one.
Answer
8
Answer for screen readers
The final answer is 8
Steps to Solve
- List the multiples of each number
List some multiples of 4 and 8 until you find a common one.
Multiples of 4: 4, 8, 12, 16, 20, ... Multiples of 8: 8, 16, 24, 32, ...
- Identify the smallest common multiple
The smallest common multiple between the two lists of multiples is the least common multiple (LCM).
From our lists, the smallest common multiple is 8.
The final answer is 8
More Information
The least common multiple (LCM) of two numbers is the smallest number that is a multiple of both numbers. In this case, 8 is the smallest number divisible by both 4 and 8.
Tips
A common mistake is to not list enough multiples to find the smallest common one, or to incorrectly identify the first common multiple. Always check if there are any smaller common multiples you may have missed.
