The greatest common factor (GCF) of two numbers is the largest positive integer that divides evenly into both numbers. To find the GCF of 32 and 40, we can list the factors of each number and identify the largest common factor.
Factors of 32: 1, 2, 4, 8, 16, 32
Factors of 40: 1, 2, 4, 5, 8, 10, 20, 40
From the lists, we can see that the largest common factor is 8. Therefore, the greatest common factor of 32 and 40 is 8.
