To find the greatest common factor (GCF) of the numbers 12, 18, and 24, we first need to determine their factors.
The factors of 12 are:
- 1, 2, 3, 4, 6, 12
The factors of 18 are:
- 1, 2, 3, 6, 9, 18
The factors of 24 are:
- 1, 2, 3, 4, 6, 8, 12, 24
Next, we identify the common factors among these three numbers. The common factors of 12, 18, and 24 are:
- 1, 2, 3, 6
Out of these common factors, the greatest one is 6. Therefore, the greatest common factor of 12, 18, and 24 is 6.
