## What is the GCF of 4 and 6?

We found the factors and prime factorization of 4 and 6.

The biggest common factor number is the GCF number.

So the greatest common factor 4 and 6 is 2..

## What is the HCF of 18?

Find the highest common factor (H.C.F) of 12 and 18. Factors of 18 = 1, 2, 3, 6, 9 and 18. Therefore, common factor of 12 and 18 = 1, 2, 3 and 6. Highest common factor (H.C.F) of 12 and 18 = 6 [since 6 is the highest common factor].

## What is the GCF of 18 and 25?

We found the factors and prime factorization of 18 and 25. The biggest common factor number is the GCF number. So the greatest common factor 18 and 25 is 1.

## 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 for 15 and 20?

Greatest common factor (GCF) of 15 and 20 is 5. We will now calculate the prime factors of 15 and 20, than find the greatest common factor (greatest common divisor (gcd)) of the numbers by matching the biggest common factor of 15 and 20.

## What is the GCF of 18 and 27?

Example: Find 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 16 and 24?

8Consider the highest common factor of 16 and 24 again. The common factors are 1, 2, 4 and 8. So, the highest common factor is 8.

## What is the GCF of 15 and 18?

The factors of 18 are 18, 9, 6, 3, 2, 1. The common factors of 15 and 18 are 3, 1, intersecting the two sets above. In the intersection factors of 15 ∩ factors of 18 the greatest element is 3. Therefore, the greatest common factor of 15 and 18 is 3.

## What is the greatest common factor 15 and 25?

Greatest common factor (GCF) of 15 and 25 is 5. We will now calculate the prime factors of 15 and 25, than find the greatest common factor (greatest common divisor (gcd)) of the numbers by matching the biggest common factor of 15 and 25.

## What is the greatest factor of 15?

The prime factors they have in common are 3 x 5. 3 x 5 = 15. The greatest common factor is 15. When two numbers have no prime factors in common, their greatest common factor is 1.

## What is the GCF of 12 and 15?

The factors of 12 are : 1, 2, 3, 4, 6, 12. 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 16 and 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…

## What is the HCF of 18 and 24?

We found the factors and prime factorization of 18 and 24. The biggest common factor number is the GCF number. So the greatest common factor 18 and 24 is 6.

## 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 GCF of 3 and 20?

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