To find the greatest common factor (GCF) of 42, 70, and 105, we first need to find the prime factorization of each number. 42 = 2 x 3 x 7 70 = 2 x 5 x 7 105 = 3 x 5 x 7 The GCF is the product of the common prime factors raised to the lowest power they appear in all three numbers. Therefore, the GCF of 42, 70, and 105 is 7.
The GCF is 5.
The GCF is 5.
The GCF is 14.
