There is neither a greatest common factor nor common factors of a single number, such as 243, 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 least common factor of 81 and 243?

The factors of 81 are 1, 3, 9, 27, and 81. The factors of 243 are 1, 3, 9, 27, 81, and 243. The common factors of 81 and 243 are 1, 3, 9, 27, and 81. Therefore, the least common factor (the smallest common factor) is 1.


What are the greatest common factors of 45 and 81?

Short answer: There are none. There is neither a greatest common factor nor common factors of a single number, such as 81, 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 81 are 1, 3, 9, 27, and 81. Examples: The common factors of 18 and 81 are 1, 3, and 9; the greatest common factor is 9. The common factors of 20 and 81 are only 1; the greatest common factor is 1. The common factors of 39 and 81 are 1 and 3; the greatest common factor is 3. The common factors of 81 and 243 are 1, 3, 9, 27, and 81; the greatest common factor is 81.


What are the factors and prime factors of 243?

243 is a composite number because it has factors other than 1 and itself. It is not a prime number.The 8 factors of 243 are 1,2,3,4,9,27,81, and 243.The factor pairs of 243 are 1 x 243, 3 x 81, and 9 x 27.The proper factors of 243 are 1, 3, 9, 27, and 81 or,if the definition you are using excludes 1, they are 3, 9, 27, and 81.The prime factors of 243 are 3, 3, 3, 3, and 3. Note: There is repetition of these factors, so if the prime factors are being listed instead of the prime factorization, usually only the distinct prime factors are listed.The distinct prime factor (listing each prime factor only once) of 243 is 3.The prime factorization of 243 is 3 x 3 x 3 x 3 x 3 or, in exponential form, is 35.NOTE: There cannot be common factors, a greatest common factor, or a least common multiple because "common" refers to factors or multiples that two or more numbers have in common.


What are all common factors of 243?

There cannot be a common factor of just one number. To be common, there needs to be at least two numbers; howver, the factors of 243 are 1, 3, 9, 27, 81, and 243.
