To find the greatest common factor (GCF) of 12, 28, and 40, you need to identify the factors of each number. 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 factors of 40 are 1, 2, 4, 5, 8, 10, 20, and 40. The greatest common factor among these numbers is 4.
The greatest common factor of 12, 28, and 40 is 4
To find the greatest common factor of numbers, you first need to split these numbers into their prime factors:
12 = 2x2x3
28 = 2x2x7
40 = 2x2x2x2x5
You then need to find which prime factors are shared between the numbers. In this case, each of the numbers uses two 2s, but no other numbers are common between them. So to find the GCF we simply multiply two 2s:
2x2=4
Thus the GCF of 12, 28 and 40 is 4.
The GCF is 4.
The GCF of 4, 12, and 28 is 4.
The greatest common factor (GCF) is often also called the greatest common divisor (GCD) or highest common factor (HCF). Keep in mind that these different terms all refer to the same thing: the largest integer which evenly divides two or more numbers. The Greatest Common Factor (GCF) of 12, 16, and 28 is 4. The GCF is 4.
The Greatest Common Factor of 28, 48 is 4.
