To find the greatest common factor (GCF) of 28, 16, and 42, we need to first find the prime factorization of each number.
28 = 2 x 2 x 7 16 = 2 x 2 x 2 x 2 42 = 2 x 3 x 7
Next, we identify the common prime factors: 2 and 7. The GCF is the product of these common prime factors, which is 2 x 7 = 14. Therefore, the GCF of 28, 16, and 42 is 14.
7 is the gcf of 28 35 and 42
GCF of 21 and 42: 21GCF of 16 and 25: 1
The GCF is 14.
The GCF is 14.
The GCF of 28, 42 and 63 is 7.The GCF is 7.
7 is the gcf of 28 35 and 42
The GCF is 7.
GCF(14, 28, 42) = 14.
The GCF of 28 and 42 is 14.
