Answer: 4Definition: A factor is a divisor - a number that will evenly divide into another number. The greatest common factor of two or more numbers is the largest factor that the numbers have in common.Method:One way to determine the common factors and greatest common factor is to find all the factors of the numbers and compare them.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 common factors are 1, 2, and 4. Therefore, the greatest common factor is 4.The greatest common factor of the numbers 28 and 40 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.

8 is the greatest common factor for 48 and 40

The greatest common factor of 1824 , 40 = 8

The GCF of 10 and 40 is 10. 10 is a factor of 40, and 10 is the largest factor of itself, so 10 is the greatest common factor of 10 and 40.

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 of 20, 28, and 40 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.
