## What is the GCF of 18 and 27?

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 HCF of 9 and 11?

gcf, hcf, gcd (9; 11) = 1: greatest (highest) common factor (divisor), calculated. Coprime numbers (relatively prime). Numbers have no common prime factors.

## What is the GCF of 12 and 9?

We found the factors and prime factorization of 9 and 12. The biggest common factor number is the GCF number. So the greatest common factor 9 and 12 is 3.

## What is the GCF of 12 and 15?

The factors of 15 are : 1, 3, 5, 15. 1 and 3 are the only common factors (numbers which are factors of both 12 and 15). Therefore, the highest common factor of 12 and 15 is 3.

## What is the GCF of 3 and 9?

Greatest common factor (GCF) of 3 and 9 is 3.

## What is the GCF of 16 and 20?

We may write the solution symbolically as GCF(20, 16) = 4. This says “the greatest common factor of 20 and 16 is 4.”

## What is the GCF of 16 and 24?

The greatest common factor of two (or more) numbers is the product of all the prime factors the numbers have in common. There are three 2’s common to both numbers, so 2*2*2 = 8 is the “greatest common factor” (GCF) of 16 and 24.

## What are the factors of 16?

Table of Factors and MultiplesFactorsMultiples1, 2, 4, 8, 16161121, 17171191, 2, 3, 6, 9, 18181261, 191913341 more rows

## What is the GCF of 12 and 18?

In terms of numbers, the greatest common factor (gcf) is the largest natural number that exactly divides two or more given natural numbers. Example 1: 6 is the greatest common factor of 12 and 18.

## What is the HCF of 16?

The factors for 16 are 1, 2, 4, 8, 16. The two numbers (12 and 16) share common factors (1, 2, 4). The greatest of these is 4 and that is the greatest common factor.

## What is the GCF of 18 and 30?

Greatest common factor (GCF) of 18 and 30 is 6. We will now calculate the prime factors of 18 and 30, than find the greatest common factor (greatest common divisor (gcd)) of the numbers by matching the biggest common factor of 18 and 30.

## What is the GCF of 20 and 12?

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 do 12 and 16 have in common?

The prime factorization of 16 is: 2 x 2 x 2 x 2. The prime factors and multiplicities 12 and 16 have in common are: 2 x 2. 2 x 2 is the gcf of 12 and 16. gcf(12,16) = 4.

## What is the GCF of 24 and 18?

Consider the numbers 18, 24, and 36. Their greatest common factor is 6. Another method of finding the greatest common factor is by using prime factorization.

## What is the HCF of 16 20?

The highest common factor of 16 and 20 is 4. We can use the prime factorization method to first determine the common factors and then the highest…
