What are the common factors and greatest common factor of 234?

Answer 1

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.

Answer 2

Short answer: There are none.

There is neither a greatest common factor nor common factors of a single number, such as 67, 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.

Answer 3

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.

Since 247 is a single number, you could say that it shares all of its factors with itself. So the greatest factor of 247 is 247

Answer 4

The 4 factors of 247 are 1, 13, 19, and 247. The factor pairs of 247 are 1 x 247 and 13 x 19.

The prime factors of 247 are 13 and 19. The prime factorization of 247 is 13 x 19.

Answer 5

Since 7 is a factor of 21, it is automatically the GCF and all of its factors are common.

Answer 6

You need at least two numbers to find a GCF.

Answer 7

You need at least two numbers to find something in common between them.

Answer 8

1, 13, 19, 247
