What are the common factor of 32?

Answer 1

Short answer: There are no "common factors" of 32.

There is neither a greatest common factor nor common factors of a single number, such as ??, 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.

Examples:

The common factors of 32 and 36 are 1, 2, and 4; the greatest common factor is 4.

The common factors of 32 and 48 are 1, 2, 4, 8, and 16; the greatest common factor is 16.

The common factors of 32 and 56 are 1, 2, 4, and 8; the greatest common factor is 8.

The common factors of 32 and 63 are only 1; the greatest common factor is 1.

The common factors of 32 and 90 are 1 and 2; the greatest common factor is 2.

The common factors of 32 and 96 are 1, 2, 4, 8, 16, and 32; the greatest common factor is 32.

The factors of 32 are 1,2,4,8,16 and 32.
The factors of 32 are 1, 2, 4, 8, 16, 32. For them to be common, they have to be compared to another set of factors.

Answer 2

For a number to have common factors, there needs to be another number for it to share common factors with. Therefore, while the number 32 has six factors, it requires another number with which to share these factors in order to have common factors.

Answer 3

There cannot be common factors of just one number. To be common there need to be at least two numbers.
