## What is the GCF of 81 and 54?

3 x 3 x 3 is the gcf of 54 and 81.

gcf(54,81) = 27..

## What is the GCF of 15 and 30?

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

## What is the GCF of 70 and 100?

The common factors of 70 and 100 are 10, 5, 2, 1, intersecting the two sets above. In the intersection factors of 70 ∩ factors of 100 the greatest element is 10. Therefore, the greatest common factor of 70 and 100 is 10.

## What is the GCF of 12 and 20?

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 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 is the GCF of 60 and 45?

We found the factors and prime factorization of 45 and 60. The biggest common factor number is the GCF number. So the greatest common factor 45 and 60 is 15.

## What is the GCF of 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 3 and 20?

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

## What is the GCF of 100?

We found the factors and prime factorization of 100 and 120. The biggest common factor number is the GCF number. So the greatest common factor 100 and 120 is 20.

## How do you solve for GCF?

To find the GCF of two numbers:List the prime factors of each number.Multiply those factors both numbers have in common. If there are no common prime factors, the GCF is 1.

## What is the GCF of 100 and 15?

The common factors of 15 and 100 are 5, 1, intersecting the two sets above. In the intersection factors of 15 ∩ factors of 100 the greatest element is 5. Therefore, the greatest common factor of 15 and 100 is 5.

## What is the HCF of 18 54 and 81?

9The HCF of 18, 54 and 81 is 9.

## What is the GCF of 10 and 15?

Greatest common factor (GCF) of 10 and 15 is 5. We will now calculate the prime factors of 10 and 15, than find the greatest common factor (greatest common divisor (gcd)) of the numbers by matching the biggest common factor of 10 and 15.

## What is the GCF of 80 100?

Greatest common factor (GCF) of 80 and 100 is 20. We will now calculate the prime factors of 80 and 100, than find the greatest common factor (greatest common divisor (gcd)) of the numbers by matching the biggest common factor of 80 and 100.

## How GCD is calculated?

In principle, greatest common divisors can be computed by determining the prime factorizations of the two numbers and comparing factors, as in the following example: to compute gcd(18, 84), we find the prime factorizations 18 = 2. 32 and 84 = 2. 3. 7, and since the “overlap” of the two expressions is 2.

## What is the highest common factor of 80?

Answer and Explanation: The greatest common factor (GCF) of 64 and 80 is 16. Prime factorization can help us get the GCF here. 64 = 1 * 64 = 1 * 2 * 32 = 1 * 2 * 2 * 16 = 1…

## 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.
