## What are 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..

## How do you solve for GCF?

The greatest common factor, or GCF, is the greatest factor that divides two numbers. To find the GCF of two numbers: List the prime factors of each number. Multiply those factors both numbers have in common.

## 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 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 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 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 GCF for 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 GCF of 24 and 66?

We found the factors and prime factorization of 24 and 66. The biggest common factor number is the GCF number. So the greatest common factor 24 and 66 is 6.
