## How do you find the GCF in math?

To find the GCF of two numbers:

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

## How do you define GCF?

The greatest number that is a factor of two (or more) other numbers. 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. Abbreviated ” GCF “. Also called “Highest Common Factor”

## 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 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.

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 2 and 9?

What is the Greatest Common Factor of 2 and 9? Greatest common factor ( GCF) of 2 and 9 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 12 and 15?

The GCF of 12 and 15 is 3.

## How do you find the GCF of two variables?

Finding the Greatest Common Factor ( GCF ): To find the GCF of two expressions:

1. Factor each coefficient into primes. Write all variables with exponents in expanded form.
2. List all factors—matching common factors in a column.
3. Bring down the common factors that all expressions share.
4. Multiply the factors as in ( Figure ).

## How do you find the GCF example?

The greatest common factor ( GCF ) of a set of numbers is the largest factor that all the numbers share. For example, 12, 20, and 24 have two common factors: 2 and 4. The largest is 4, so we say that the GCF of 12, 20, and 24 is 4. GCF is often used to find common denominators.
