## What is the greatest common factor of 6 and?

The greatest common factor (GCF or GCD or HCF) of a set of whole numbers is the largest positive integer that divides evenly into all numbers with zero remainder.

For example, for the set of numbers 18, 30 and 42 the GCF = 6..

## 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 is the GCF of 10 15 and 20?

We found the factors and prime factorization of 15 and 20. The biggest common factor number is the GCF number. So the greatest common factor 15 and 20 is 5.

## 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 do 15 and 20 have in common?

The factors of 20 are 20, 10, 5, 4, 2, 1. The common factors of 15 and 20 are 5, 1, intersecting the two sets above. In the intersection factors of 15 ∩ factors of 20 the greatest element is 5. Therefore, the greatest common factor of 15 and 20 is 5.

## 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 7 and 10?

The prime factors and multiplicities 7 and 10 have in common are: 1. 1 is the gcf of 7 and 10. gcf(7,10) = 1.

## What is the HCF of 10 15?

Find the highest common factor (H.C.F) of 15 and 10. Factors of 10 = 1, 2, 5 and 10. Therefore, common factor of 15 and 10 = 1 and 5. Highest common factor (H.C.F) of 15 and 10 = 5.

## 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 15 and 30?

Greatest common factor (GCF) of 15 and 30 is 15.

## 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 4 and 5?

Greatest common factor (GCF) of 4 and 5 is 1. We will now calculate the prime factors of 4 and 5, than find the greatest common factor (greatest common divisor (gcd)) of the numbers by matching the biggest common factor of 4 and 5.

## What is the GCF of 24?

Answer and Explanation: 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 HCF of 30?

Factors of 30 (Thirty) = 1, 2, 3, 5, 6, 10, 15 and 30. Factors of 24 (Twenty four) = 1, 2, 3, 4, 6, 8, 12 and 24. Therefore, common factor of 30 (Thirty) and 24 (Twenty four = 1, 2, 3, and 6. Highest common factor (H.C.F) of 30 (Thirty) and 24 (Twenty four = 6.

## What is the GCF for 15?

We found the factors and prime factorization of 15 and 25. The biggest common factor number is the GCF number. So the greatest common factor 15 and 25 is 5.

## What is the GCF of 3 15 and 9?

We found the factors and prime factorization of 9 and 15. The biggest common factor number is the GCF number. So the greatest common factor 9 and 15 is 3.

## What is the HCF of 18 and 6?

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