## 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 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 24 and 36?

The GCF of 24 and 36 is 12. ‘ GCF ‘ means ‘ greatest common factor ‘. That’s the greatest, or largest, factor that the two numbers share.

## 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 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 18?

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

## What is the GCF of 10 and 15?

Answer: GCF of 10 and 15 is 5.

## What is the GCF of 16 and 24?

Method 2: GCF of 16 and 24 by Listing the Common Factors Common Factors of 24 and 16: 1, 2, 8 and the greatest among them is 8.

## 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 12 and 15?

The GCF of 12 and 15 is 3.

## What is the GCF of 12 and 24?

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

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

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’s the GCF of 24?

List all possible whole-number dimensions the garden can have. The whole-number dimensions of this rectangular garden are the factors of the number 24. The following statements can be made about the factors of 24: The factors of 24 are: 1, 2, 3, 4, 6, 8, 12 and 24 since each of these numbers divides exactly into 24.
