Find the greatest common factor of 18 and 75?
The greatest common factor (GCF) is 3.
How do you find the greatest common factor of 45 using prime factorization?
You do not. To have a greatest common factor, you need two or more numbers. A common factor is a factor that two or more number have in common. However, the prime factorization of all the numbers will help you find the greatest common factor. The greatest common factor will be the prime factors they have in common multiplied together. Example: The prime factors of 45 are 3, 3, and 5. The prime factors of 60 are 2, 2, 3, and 5. The common prime factors are 3 and 5, so the greatest common factor is 3 x 5 = 15.

What is the highest common factor of 24 and 39?
There cannot be a greatest common factor (GCF) of just one number. To be common there need to be at least two numbers. If you find all the factors of two or more numbers, and you find some factors are the same ("common"), then the largest of those common factors is the Greatest Common Factor.
What is the greatest common factor of 39 and 30?
The greatest common factor of 30 and 39 is 3.

The greatest common factor of 24 and 57 is 3.
What is the greatest common factor of 3 and 36?
The greatest common factor (GCF) of 3 and 36 is 3. This is because 3 is a factor of both 3 and 36, and it is the largest factor that they have in common. To find the GCF, you can list the factors of each number and identify the largest one they share.
Find the greatest common factor of 6 and 9?
The GCF is 3.

The greatest common factor of 3 and 57 is 3
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.
