Best Answer

The greatest common factor (GCF) of 12, 24, and 42 is the largest number that divides evenly into all three numbers. To find the GCF, you can first list the factors of each number: 12 (1, 2, 3, 4, 6, 12), 24 (1, 2, 3, 4, 6, 8, 12, 24), and 42 (1, 2, 3, 6, 7, 14, 21, 42). The common factors among the three numbers are 1, 2, 3, and 6. Therefore, the greatest common factor of 12, 24, and 42 is 6.
