What is the greatest common factor of45 and 75?

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 6 and 45?

The GCF of 6 and 45 is 3. A factor is a divisor - a number that will evenly divide into another number. The greatest common factor of two or more numbers is the largest factor that both numbers have in common. One way to determine the common factors and greatest common factor is to find all the factors of the numbers and compare them. The factors of 6 are 1, 2, 3, and 6. 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.

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 greatest common factor of 10 and 45?

The GCF of 10 and 45 is 5 The factors of 10 are 1, 2, 5, and 10. The factors of 45 are 1, 3, 5, 9, 15, and 45. The largest factor they have in common is 5, so 5 is the greatest common factor. Or, you can use prime factors. The prime factors of 10 are 2 and 5. The prime factors of 45 are 3, 3, and 5. The prime factors they have in common are a single 5, so 5 is the greatest common factor.
