Steps to Solve
- List the factors of both numbers
First, we need to find all the factors of both 50 and 30.
- The factors of 50 are: 1, 2, 5, 10, 25, 50
- The factors of 30 are: 1, 2, 3, 5, 6, 10, 15, 30
- Identify the common factors
Next, we find the factors that both numbers share.
- The common factors of 50 and 30 are: 1, 2, 5, 10
- Determine the greatest common factor
Finally, we identify the largest factor from the common factors list.
- The greatest common factor (GCF) is 10.
