The least common factor of 8 and 3 is 1.
Steps to Solve
- List the factors of each number
To find the least common factor, first, we need to identify the factors of both 8 and 3.
- The factors of 8 are: 1, 2, 4, 8
- The factors of 3 are: 1, 3
- Identify common factors
Next, we will look for the factors that both numbers share.
- Common factors of 8 and 3: 1
- Select the least common factor
The least common factor is the smallest positive integer from the list of common factors.
- The only common factor is 1.
The least common factor of 8 and 3 is 1.
More Information
The least common factor is always 1 for any pair of integers since 1 is a factor of every integer.
Tips
- Confusing least common factor with least common multiple; the least common factor is always 1 for any two numbers, whereas the least common multiple varies.
- Forgetting to list down the factors before looking for common ones. Always start by identifying the factors first.
