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.

A polynomial of degree zero is a constant term

The grouping method of factoring can still be used when only some of the terms share a common factor A True B False

The sum or difference of p and q is the of the x-term in the trinomial

A number a power of a variable or a product of the two is a monomial while a polynomial is the of monomials

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.


What are the factors of 243?

The positive integer factors of 243 are 1, 3, 9, 27, 81, and 243 The factor pairs of 243 are (1, 243), (3, 81), and (9, 27).


What is the least common factor of 45 and 81?

The least common factor of any numbers is typically 1. The factors of 45 are 1, 3, 5, 9, 15, and 45. The factors of 81 are 1, 3, 9, 27, and 81. The common factors are 1, 3, and 9. The least (smallest) common factor is 1.


What are the common factors and greatest common factor of 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 is the greatest common factor of 81?

There is not a greatest common factor of 81 because there cannot be a greatest 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.The factors of 81 are 1, 3, 9, 27, and 81.The prime factors of 81 are 3, 3, 3, and 3.Examples:The greatest common factor of 54 and 81 is 27.The greatest common factor of 81 and 117 is 9.You need at least two numbers to find a GCF.You need at least two numbers to find a GCF.
