The GCF is 14.
The greatest common factor (GCF) of 42 and 70 is the largest number that divides evenly into both 42 and 70. To find the GCF, we first list the factors of each number: 42 (1, 2, 3, 6, 7, 14, 21, 42) and 70 (1, 2, 5, 7, 10, 14, 35, 70). The largest number that appears in both lists is 14, so the GCF of 42 and 70 is 14.
