What is the greatest common factor of 12 18 and 28?

Answer 1

The greatest common factor of 12, 18, and 28 is 2.

The prime factorization of 12 is 2*2*3
The prime factorization of 18 is 2*3*3
The prime factorization of 28 is 2*2*7

So the greatest common factor of the set is 2.

Answer 2

The greatest common factor (GCF) of 12, 18, and 28 is the largest number that divides evenly into all three numbers. To find the GCF, we need to determine the factors of each number. The factors of 12 are 1, 2, 3, 4, 6, and 12; the factors of 18 are 1, 2, 3, 6, 9, and 18; and the factors of 28 are 1, 2, 4, 7, 14, and 28. The largest number that appears in all three lists is 2, making the GCF of 12, 18, and 28 equal to 2.

Answer 3

Well, isn't that just a happy little math question? Let's find the greatest common factor of 12, 18, and 28 together. The factors of 12 are 1, 2, 3, 4, 6, and 12, the factors of 18 are 1, 2, 3, 6, 9, and 18, and the factors of 28 are 1, 2, 4, 7, 14, and 28. The greatest common factor among them all is 2. Just like painting, math is all about finding harmony and beauty in numbers!
