What are the common factors and greatest common factor of 3?
There is neither a greatest common factor nor common factors of a single number, such as 3, 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 3 are 1 and 3. The prime factor of 3 is 3. Examples: The common factors of 3 and 20 are only 1; the greatest common factor is 1. The common factors of 3 and 81 are 1 and 3; the greatest common factor is 3.
Does any number that has 3 as a factor also have 9 as a factor?
No. 6 has 3 as a factor. 12 has 3 as a factor.
What is the greatest factor of 3?
3 is the greatest factor of 3.
What is the greatest common factor of 999?
There is not a greatest common factor of a single number, such as 999, 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 999 are 1, 3, 9, 27, 37, 111, 333, and 999. The prime factors of 999 are 3, 3, 3, and 37. Examples: The greatest common factor of 54 and 999 is 27. The greatest common factor of 185 and 999 is 37. The greatest common factor of 999 and 1001 is 1.
What is the greatest common factor of 69?
There is not a greatest common factor of a single number, such as 69, 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 69 are 1, 3, 23, and 69. The prime factors of 69 are 3 and 23. The prime factorization of 69 is 3 x 23. Examples: The greatest common factor of 51 and 69 is 3. The greatest common factor of 32 and 69 is 1. The greatest common factor of 69 and 115 is 23. You need at least two numbers to find a GCF. If that's 6 and 9, the GCF is 3.
