There is neither a greatest common factor nor common factors of a single number, such as 128, because there cannot be any form of common factor without two or more numbers to compare. Common factors are factors that the numbers being compared have in common. The greatest common factor is the largest factor that all the numbers being compared have in common. Thus, since there are not two or more numbers to compare, there are neither common factors nor a greatest common factor.

What is the greatest common factor of 128 and 245?

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 both numbers have in common. 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 128 are 1, 2, 4, 8, 16, 32, 64, and 128. The factors of 245 are 1, 5, 7, 35, 49, and 245. The only common factor is 1. Therefore, the greatest common factor is 1.

What is the greatest common factor of 48 80 and 128?

Answer: 16 One way to determine the greatest common factor is to find all the factors of the numbers and compare them. The factors of 48 are 1, 2, 3, 4, 6, 8, 12, 16, 24, and 48. The factors of 80 are 1, 2, 4, 5, 8, 10, 16, 20, 40, and 80. The factors of 128 are 1, 2, 4, 8, 16, 32, 64, and 128. The common factors are 1, 2, 4, 8, and 16. Therefore, the greatest common factor is 16. The greatest common factor can also be calculated by identifying the common prime factors and multiplying them together. The prime factors of 48 are 2, 2, 2, 2, and 3. The prime factors of 80 are 2, 2, 2, 2, and 5. The prime factors of 128 are 2, 2, 2, 2, 2, 2, and 2. The prime factors in common are 2, 2, 2, and 2, so the greatest common factor is 2 x 2 x 2 x 2 = 16. Another way to approach this is to look at the differences between the numbers. The greatest common factor of two or more numbers cannot be larger than the smallest difference between the numbers. The difference between 48 and 80 is 32. The difference between 80 and 128 is 48. Also, the greatest common factor must be a factor of the differences between the numbers. If we find the greatest common factor of 32 and 48, we will have the greatest common factor of 48, 80, and 128. The difference between 32 and 48 is 16, so the greatest possible common factor between 32 and 48 is 16. Since 16 is a factor of both 32 and 48, it is their greatest common factor, and thus the greatest common factor of 48, 80, and 128.


What is the greatest common factor of 306?

There is not a greatest common factor of a single number, such as 306, because there cannot be a greatest common factor without two or more numbers to compare. Common factors are factors that the numbers being compared have in common. The greatest common factor is the largest factor that all the numbers being compared have in common. The factors of 306 are 1, 2, 3, 6, 9, 17, 18, 34, 51, 102, 153, and 306. The prime factors of 306 are 2, 3, 3, and 17. Examples: The greatest common factor of 27 and 306 is 9. The greatest common factor of 128 and 306 is 2. The greatest common factor of 306 and 765 is 153.

Which is not the greatest common factor of 128?

There cannot be a greatest common factor of just one number. To be common there need to be at least two numbers. If you find all the factors of two or more numbers, and you find some factors are the same ("common"), then the largest of those common factors is the Greatest Common Factor.

What is the greatest common factor of 48 80 and 128?

Answer: 16 One way to determine the greatest common factor is to find all the factors of the numbers and compare them. The factors of 48 are 1, 2, 3, 4, 6, 8, 12, 16, 24, and 48. The factors of 80 are 1, 2, 4, 5, 8, 10, 16, 20, 40, and 80. The factors of 128 are 1, 2, 4, 8, 16, 32, 64, and 128. The common factors are 1, 2, 4, 8, and 16. Therefore, the greatest common factor is 16. The greatest common factor can also be calculated by identifying the common prime factors and multiplying them together. The prime factors of 48 are 2, 2, 2, 2, and 3. The prime factors of 80 are 2, 2, 2, 2, and 5. The prime factors of 128 are 2, 2, 2, 2, 2, 2, and 2. The prime factors in common are 2, 2, 2, and 2, so the greatest common factor is 2 x 2 x 2 x 2 = 16. Another way to approach this is to look at the differences between the numbers. The greatest common factor of two or more numbers cannot be larger than the smallest difference between the numbers. The difference between 48 and 80 is 32. The difference between 80 and 128 is 48. Also, the greatest common factor must be a factor of the differences between the numbers. If we find the greatest common factor of 32 and 48, we will have the greatest common factor of 48, 80, and 128. The difference between 32 and 48 is 16, so the greatest possible common factor between 32 and 48 is 16. Since 16 is a factor of both 32 and 48, it is their greatest common factor, and thus the greatest common factor of 48, 80, and 128.
