lcm 5 and 3
Understand the Problem
The question is asking to find the least common multiple (LCM) of the numbers 5 and 3. To solve this, we will identify the multiples of each number and find the smallest one that is common to both sets.
Answer
15
Answer for screen readers
The final answer is 15
Steps to Solve
- List the multiples of each number
First, list a few multiples of each number to identify the common multiples:
For 5: 5, 10, 15, 20, 25, ... For 3: 3, 6, 9, 12, 15, ...
- Identify the common multiples
Next, identify the smallest common multiple in both lists:
Common multiples: 15, 30, ...
- Select the smallest common multiple
The smallest number that appears in both lists of multiples is 15.
The final answer is 15
More Information
The least common multiple (LCM) of two numbers is the smallest number that is a multiple of both. In this case, 15 is the smallest common multiple of 5 and 3.
Tips
A common mistake is to stop listing multiples too early, before finding the common one. Ensure enough multiples are listed to identify the smallest common one.
