What is the greatest common factor of 306 and 459?

Answer 1

Short answer: There are none.

There is neither a greatest common factor nor common factors of a single number, such as 145, 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.

The factors of 145 are 1, 5, 29, and 145.

Examples:

The common factors of 30 and 145 are 1 and 5; the greatest common factor is 5.

The common factors of 145 and 149 are only 1; the greatest common factor is 1.

The common factors of 145 and 174 are 1 and 29; the greatest common factor is 29.

Answer 2

Short answer: There are none.

There is neither a greatest common factor nor common factors of a single number, such as 459, 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. The factors of 459 are 1, 3, 9, 17, 27, 51, 153, and 459. Examples: The common factors of 18 and 459 are 1, 3, and 9; the greatest common factor is 9.

The common factors of 102 and 459 are 1, 3, 17, and 51; the greatest common factor is 51.

The common factors of 144 and 459 are 1 and 3; the greatest common factor is 3.

Answer 4

You need at least two numbers to find a GCF.

Answer 5

You need at least two numbers to find a GCF.

If that's 4 and 60, the GCF is 4.

Answer 6

The prime factors of 4599 are 3, 7, and 73.

32 x 7 x 73 = 4599

Answer 7

The GCF is 153.
