What is the greatest common factor of 36 and 243?
The GCF of 36 and 243 is 9.
What are the common factors and greatest common factor of 243?
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 is the highest common factor of 36 and 243?
The Greatest Common Factor (GCF) is 9. 36 = 2 x 2 x 3 x3 243 = 3 x 3 x 3 x 3 x 3 Common prime factors = 3 x 3 = 9
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 is the greatest common factor of 90 and 243?

What is the greatest common factor of 36 and 243?
The GCF of 36 and 243 is 9.
What is the greatest common factor of 7 and 243?
The greatest common factor of 7 and 243 is 1. Prime factorizations: 7 = 7 243 = 3 x 3 x 3 x 3 common factors - no primes, so only common factor is 1: 7 x 1 = 7 243 x 1 = 243
