# What Is The Greatest Common Factor Of 8 And 20

The greatest common factor (GCF) of two numbers is the largest number that divides evenly into both numbers. For example, the GCF of 8 and 20 is 4. To find the GCF of 8 and 20, start by listing the factors of each number.

The factors of 8 are 1, 2, 4, and 8. The factors of 20 are 1, 2, 4, 5, 10, and 20. The common factors of 8 and 20 are 1, 2, and 4.

The greatest of these is 4, so the greatest common factor of 8 and 20 is 4.

The greatest common factor of 8 and 20 is 4.

## What is the greatest common factor of 4 16 and 24

The greatest common factor of 4, 16, and 24 is 4. This is because 4 is the only number that is a common factor of all three numbers. To find the greatest common factor of three numbers, you can use the greatest common factor algorithm.

This algorithm is based on the fact that the greatest common factor of two numbers is the smaller number if the two numbers are equal, and the difference between the two numbers if they are not equal. To find the greatest common factor of three numbers, you first find the greatest common factor of the two smaller numbers, and then find the greatest common factor of the resulting number and the remaining number. In this case, the greatest common factor of 4 and 16 is 4, and the greatest common factor of 4 and 24 is 4.

## What is the greatest common factor of 12 and 20?

The greatest common factor of 12 and 20 is 4. To find the greatest common factor of two numbers, you need to find the largest number that is a factor of both numbers. In this case, the largest number that is a factor of both 12 and 20 is 4.

To find the greatest common factor of two numbers, you can also use the prime factorization method. To do this, you would need to list out the prime factors of both numbers. For 12, the prime factors are 2, 2, and 3.

For 20, the prime factors are 2, 2, and 5. When you compare the two lists, you can see that the common factors are 2 and 2. The greatest of these is 2, so the greatest common factor of 12 and 20 is 2.

## What is the greatest common factor of 16 and 20?

The greatest common factor of 16 and 20 is 4. This is because 4 is the largest number that both 16 and 20 can be divided by evenly. To find the greatest common factor of two numbers, you can simply list out the factors of each number and then find the largest number that appears on both lists.

In this case, the factors of 16 are 1, 2, 4, 8, and 16, while the factors of 20 are 1, 2, 4, 5, 10, and 20. As you can see, the number 4 appears on both lists, so we know that 4 is the greatest common factor of 16 and 20.

## What is the greatest common factor of 15 and 20?

The greatest common factor of 15 and 20 is 5. This is because 5 is the largest number that both 15 and 20 can be divided by evenly. To find the greatest common factor of two numbers, you can use the prime factorization method.

This involves finding the prime factors of each number and then finding the common factors between the two numbers. For 15, the prime factors are 3 and 5. For 20, the prime factors are 2 and 5.

The common factors between the two numbers are 5. Therefore, the greatest common factor of 15 and 20 is 5.

## What is the greatest common factor of 12 and 8

The greatest common factor (GCF) of 12 and 8 is 4. We can find the GCF by listing the factors of each number and finding the largest number that appears on both lists. The factors of 12 are 1, 2, 3, 4, 6, and 12.

The factors of 8 are 1, 2, 4, and 8. The largest number that appears on both lists is 4, so 4 is the GCF of 12 and 8.

## What is the lcm of 8 and 20

The lcm of 8 and 20 is 40. To find the lcm of two numbers, you can use the greatest common divisor (gcd) method. This involves finding the greatest number that both 8 and 20 share as a divisor and then multiplying that number by the other number in the equation.

In this case, the greatest number that both 8 and 20 share as a divisor is 4. So, if you multiply 4 by the other number in the equation (20), you get 40. The lcm is a important concept in mathematics, especially when working with fractions.

The lcm is the smallest number that both 8 and 20 will divide into evenly. This is important to know because it means that any fraction with a denominator of 8 or 20 can be reduced to a lower fraction by dividing both the numerator and denominator by the lcm.

## What is the greatest common factor of 18 and 12?

The greatest common factor of 18 and 12 is 6. To find the greatest common factor of two numbers, you need to find the largest number that is a factor of both numbers. In this case, the largest number that is a factor of both 18 and 12 is 6.

Therefore, the greatest common factor of 18 and 12 is 6.

## Greatest common factor of 12 and 16

The greatest common factor (GCF) of two numbers is the largest number that is a factor of both numbers. To find the GCF of 12 and 16, we need to find the factors of each number and then find the largest number that is common to both lists of factors. The factors of 12 are 1, 2, 3, 4, 6, and 12.

The factors of 16 are 1, 2, 4, 8, and 16. The largest number that is common to both lists is 4, so the GCF of 12 and 16 is 4. We can also use the prime factorization method to find the GCF of two numbers.

To do this, we need to express each number as a product of prime factors and then find the largest number that is common to both products. The prime factorization of 12 is 2 x 2 x 3. The prime factorization of 16 is 2 x 2 x 2 x 2.

## What is the GCF and LCM of 8 and 20?
