Final answer:
The greatest common factor (GCF) of 4 and 6 is 2, which is the largest number that divides both 4 and 6 without leaving a remainder.
Step-by-step explanation:
The greatest common factor (GCF) refers to the largest factor that two or more numbers have in common. To find the GCF of 4 and 6, we need to list the factors of each:
- Factors of 4: 1, 2, 4
- Factors of 6: 1, 2, 3, 6
The common factors of 4 and 6 are 1 and 2. However, the greatest of these is 2, making it the GCF of 4 and 6.
