What Is the Gcf of 12 and 28?

The greatest common factor (GCF) of 12 and 28 is 4.

We can find the GCF of two numbers by listing the factors of each number and finding the largest number that appears in both lists. The factors of 12 are 1, 2, 3, 4, 6, and 12. The factors of 28 are 1, 2, 4, 7, 14, and 28. The largest number that appears in both lists is 4, so the GCF of 12 and 28 is 4.

We can also find the GCF of two numbers by using the prime factorization method. To find the prime factorization of a number, we write the number as a product of its prime factors. The prime factors of 12 are 2 × 2 × 3, and the prime factors of 28 are 2 × 2 × 7. When we write the numbers as products of their prime factors, we see that they have two factors of 2 in common. Therefore, the GCF of 12 and 28 is 4.

There are a few other methods we can use to find the GCF of two numbers, but the method described above is the most common.

The number 12 is evenly divisible by 1, 2, 3, 4, 6, and 12. The number 28 is evenly divisible by 1, 2, 4, 7, 14, and 28. The largest number that is evenly divisible by both 12 and 28 is 28.

A fresh viewpoint: Roman Number

The greatest common divisor (GCD) of two or more non-zero integers is the largest positive integer that divides both numbers without leaving a remainder. For example, the GCD of 8 and 12 is 4.

The GCD of two or more non-zero numbers is always positive, even if one or both of the numbers are negative. However, the GCD of two or more zero numbers is always zero.

The GCD of 12 and 28 can be found using the Euclidean algorithm, which is a method for finding the GCD of two numbers that is based on the observation that the GCD of two numbers also divides their difference.

The Euclidean algorithm is as follows:

1. Take the larger number and subtract the smaller number from it. In our case, this would be 28 – 12 = 16. 2. Take the result from the previous step and apply the same process to it and the smaller number. In our case, this would be 16 – 12 = 4. 3. Repeat step 2 until the result is zero. In our case, the result is 4 – 0 = 4, so the GCD of 12 and 28 is 4.

The Euclidean algorithm can also be used to find the GCD of more than two numbers. For instance, the GCD of 12, 28, and 40 can be found by first finding the GCD of 12 and 28, which is 4, and then finding the GCD of 4 and 40, which is also 4.
