## What is the greatest common factor of 16 18 and 30?

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 18 and 9?

We found the factors and prime factorization of 9 and 18. The biggest common factor number is the GCF number. So the greatest common factor 9 and 18 is 9.

## 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 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?

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 14 and 21?

We found the factors and prime factorization of 14 and 21. The biggest common factor number is the GCF number. So the greatest common factor 14 and 21 is 7.

## 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 gcf of 15 and 18 can be obtained like this: The factors of 15 are 15, 5, 3, 1. 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.

## What is the GCF 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 9 and 3?

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

## What is the GCF of 15 and 30?

The common factors of 15 and 30 are 1, 3, 5, and 15. The greatest common factor is 15.

## What is the GCF of 9 and 15?

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?

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 45?

The ‘GCF’ is the ‘greatest common factor’ that is shared between two numbers. Between 18 and 45, the GCF is 9, and here’s how you know.
