What is the greatest common factor of 54 and 81?

The GCF of 54 and 81 is 27One way to determine the greatest common factor is to find all the factors of the numbers and compare them.The factors of 54 are 1, 2, 3, 6, 9, 18, 27, and 54.The factors of 81 are 1, 3, 9, 27, and 81.The common factors are 1, 3, 9, and 27. Therefore, the greatest common factor is 27.The greatest common factor can also be calculated by identifying the common prime factors and multiplying them together.The prime factors of 54 are 2, 3, 3, and 3.The prime factors of 81 are 3, 3, 3, and 3.The prime factors in common are 3, 3, and 3, so the greatest common factor is 3 x 3 x 3 = 27. Factors of 54: 1 2 3 6 9 18 27 54 Factors of 81: 1 3 9 27 81 The GCF of 54 and 81 is 27The Greatest Common Factor (GCF) is: 27 .27.


What are the factors of 54 81?

The factors of 54 are: 1, 2, 3, 6, 9, 18, 27, 54 The factors of 81 are: 1, 3, 9, 27, 81


What are the common factors of 54 and 81?

54 = 2 x 3^3 81 = 3^4 Therefore factors of 54 are: 1 2 3 6 = 2 x 3 9 = 3^2 18 = 2 x 3^2 27 = 3^3 54 Factors of 81 are: 1 3 9 = 3^2 27 = 3^3 81 Common factors are thus: 1, 3, 9, 27


What are the factors of 27 54 and 81?

The factors of 27 are: 1, 3, 9, 27 The factors of 54 are: 1, 2, 3, 6, 9, 18, 27, 54 The factors of 81 are: 1, 3, 9, 27, 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.
