What is the gcf of 18 and 24?

The greatest common factor (GCF) of 18 and 24 is 6. This is because 6 is the largest number that divides both 18 and 24 without leaving a remainder. Another way to find the GCF is to list the factors of each number and find the largest one that they have in common, in the case of 18 and 24, the factors are:

Factors of 18: 1, 2, 3, 6, 9, 18 Factors of 24: 1, 2, 3, 4, 6, 8, 12, 24

The largest factor they have in common is 6, therefore the GCF of 18 and 24 is 6.
