## How do you explain GCF?

When we find all the factors of two or more numbers, and some factors are the same (“common”), then the largest of those common factors is the Greatest Common Factor. Example: the GCF of 12 and 16 is 4, because 1, 2 and 4 are common factors of both 12 and 16, and 4 is the greatest of them.

## How do you find the GCF in math?

To find the GCF of two numbers:

- List the prime factors of each number.
- Multiply those factors both numbers have in common. If there are no common prime factors, the GCF is 1.

## What is the GCF of 24 and 36?

GCF of 24 and 36 is 12, the highest among the common factors.

## What is the GCF of 12 and 30?

Earlier we found that the Common Factors of 12 and 30 are 1, 2, 3 and 6, and so the Greatest Common Factor is 6. The Greatest Common Factor of 12 and 30 is 6.

## What is the GCF of 18?

The factors of 18 are 1, 2, 3, 6, 9, 18. The factors of 27 are 1, 3, 9, 27. The common factors of 18 and 27 are 1, 3 and 9. The greatest common factor of 18 and 27 is 9.

## What is the GCF of 12 and 18?

Example 1: 6 is the greatest common factor of 12 and 18.

## What is the GCF of 18 and 24?

18 and 24 share one 2 and one 3 in common. We multiply them to get the GCF, so 2 * 3 = 6 is the GCF of 18 and 24.

## What is the GCF of 12 and 20?

The common factors of 12 and 20 are 1, 2 and 4. The greatest common factor of 12 and 20 is 4. To find the Greatest Common Factor ( GCF ) of two or more whole numbers, follow this procedure: Make a list of factors for each whole number.

## What is the GCF of 6 and 9?

What is the Greatest Common Factor of 6 and 9? Greatest common factor (GCF ) of 6 and 9 is 3. We will now calculate the prime factors of 6 and 9, than find the greatest common factor ( greatest common divisor (gcd )) of the numbers by matching the biggest common factor of 6 and 9.

## What is the GCF of 36 12 and 24?

The common factors for 24, 36, 12 24, 36, 12 are 1,2,3,4,6, 12 1, 2, 3, 4, 6, 12. The GCF (HCF) of the numerical factors 1,2,3,4,6, 12 1, 2, 3, 4, 6, 12 is 12.

## What is the GCF of 36 and 54?

Answer: GCF of 36 and 54 is 18.

## What is the GCF of 24 36 and 72?

Step-by-step explanation: Looking at these three numbers, we see that the biggest number they share is of the form:, where is just 12.

## What is the GCF of 30?

The prime factors of 30 are 2 x 3 x 5. The prime factors they have in common are 3 x 5. 3 x 5 = 15. The greatest common factor is 15.

## What is the GCF of 3 and 20?

Greatest common factor ( GCF) of 3 and 20 is 1.

## What is the GCF of 12 and 24?

Greatest common factor ( GCF) of 12 and 24 is 12.
