What is the Least common factor of 64 and 81?
The factors of 64 are all 2s and the factors of 81 are all 3s. The greatest common factor is 1, since they have no factors in common. ■
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.
Is 6 a factor from least to greatest 81?
No, it is not.
What is the GCF of 81 135?
The GCF of 81 135 is 27
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 greatest common factors for 37 and 81?
The GCF is: 1
What are the greatest common factors in 45 36 81?
9
What is the greatest common factor for 18 and 81?
The factors of 18 are 1, 2, 3, 6, 9, and 18. The factors of 81 are 1, 3, 9, 27, and 81. The common factors are 1, 3, and 9. Therefore, the greatest common factor is 9. You can also determine the greatest common factor from the prime factors. The prime factors of 18 are 2, 3, and 3. The prime factors of 81 are 3, 3, 3, and 3. The prime factors in common are 3 and 3, so the greatest common factor is 3 x 3 = 9.
