The prime factorization of 12 is: 2 x 2 x 3 = 12
However, 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 12 and 54?
The GCF of 12 and 54 is 6. To find the GCF, write the prime factorizations of each number.The prime factorization of 12 is 2*2*3The prime factorization of 54 is 2*3*3*3The factors in common are 2*3 = 6, so that is the GCF.
Can you use prime factorization fot the gcf?
YES. Prime factorization can be used to get the GCF.Example:Prime factorization of:12 = 2 x 2 x 324 = 2 x 2 x 3 x 2============GCF=2 x 2 x 3GCF=12
What is the greatest common factor of 12 and 48?
Since 12 is a factor of 48, the GCF of 12 and 48 is 12.12.12. 12/12 = 148/12 = 4GCF or 12 and 48 = 12Prime factorization of:12 = 2 * 2 * 348 = 2 * 2 * 3 * 2 * 2=============GCF=2* 2 * 3 = 12
What is the greatest common factor of 12 60 and 68?
To find the greatest common factor (GCF) of 12, 60, and 68, we first need to find the prime factorization of each number. The prime factorization of 12 is 2^2 * 3, the prime factorization of 60 is 2^2 * 3 * 5, and the prime factorization of 68 is 2^2 * 17. The GCF is the product of the common prime factors raised to the lowest power, which in this case is 2^2 = 4. Therefore, the greatest common factor of 12, 60, and 68 is 4.
What is the HCF of 12 18 and 24?
The GCF is 6.
