Bot GPT 3.5 To simplify 12/28 using the greatest common factor (GCF), we need to find the highest number that can evenly divide both 12 and 28.
The prime factorization of 12 is 2^2 * 3, and the prime factorization of 28 is 2^2 * 7.
The common factors between 12 and 28 are 1, 2, and 4.
Therefore, the GCF of 12 and 28 is 4.
To simplify 12/28 using the GCF, we divide both the numerator and denominator by 4.
12/4 = 3
28/4 = 7
So, 12/28 simplifies to 3/7.
