What is the greatest common factor of 56 84 and 140?

Answer 1

To find the greatest common factor (GCF) of 56, 84, and 140, we first need to factor each number. The prime factorization of 56 is 2^3 * 7, 84 is 2^2 * 3 * 7, and 140 is 2^2 * 5 * 7. To find the GCF, we look for the highest power of each prime factor that appears in all three factorizations, which in this case is 2^2 * 7, resulting in a GCF of 28.

Answer 2

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 50 and 140 is 10

Answer 3

The greatest common factor of 56 and 140 is 28.

28

The GCF of 56 and 140 is 28. This gives 2 and 5 respectively. There are no further common factors between 2 and 5 aside from 1.

Answer 4

Factors for 56 are: 1, 2, 4, 7, 8, 14, 28, 56

Factors for 84 are: 1, 2, 3, 4, 6, 7, 12, 14, 21, 28, 42, 84

Factors for 140 are: 1, 2, 4, 5, 7, 10, 14, 20, 28, 35, 70, 140

Greatest common factor: 28

Answer 5

The GCF is 28.

Answer 6

The GCF is 2.

Answer 7

28, and it's the "GCF".
