The first step to finding the common prime factors is to list the prime factors of both numbers. For 12 and 45, the prime factors are:
12 = 2x2x3
45 = 3x3x5
The next step is to identify which prime factors are shared by both. In this case, both use a 3. Thus, 3 is the only common prime factor of 12 and 45.

What is the greatest common factor of 24 and 45?
The GCF of 24 and 45 is 3. One way to determine the greatest common factor is to find all the factors of the numbers and compare them. The factors of 24 are 1, 2, 3, 4, 6, 8, 12, and 24. The factors of 45 are 1, 3, 5, 9, 15, and 45. The common factors are 1 and 3. Therefore, the greatest common factor is 3. The greatest common factor can also be calculated by identifying the common prime factors and multiplying them together. The prime factors of 24 are 2, 2, 2, and 3. The prime factors of 45 are 3, 3, and 5. The prime factors in common are a single 3, so the greatest common factor is 3.

What is the common factors of 45?
There cannot be a common factor 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.
