What is the gcf of 40 and 24?

The greatest common factor (GCF) of two numbers is the largest number that divides both of them without leaving a remainder.

To find the GCF of 40 and 24, we need to find the common factors of both numbers. The factors of 40 are 1, 2, 4, 5, 8, 10, 20, and 40. The factors of 24 are 1, 2, 3, 4, 6, 8, 12, and 24. The common factors of 40 and 24 are 1, 2, 4, and 8.

Therefore, the GCF of 40 and 24 is 8.
