What is the gcf of 9 27 54?
9 is the greatest common factor in these numbers. You are left with 1, 3 and 6 respectively. You cannot further reduce these by common factors as one of them has been reduced to one.
What is the greatest common factor of 96 and 108?
First reduce each number to its prime factors:96 = 2 x 2 x 2 x 2 x 2 x 3108 = 2 x 2 x 3 x 3 x 3select only the numbers that appear twice in each list (ignoring multiple instances of the same number)Thus the greatest common factor is 2 x 2 x 3 = 12
How do you factor out the greatest common factor?
divide everything by the number/variable all terms have in common. Ex: y^3-y^2-y. The gcf is y, so you would reduce it to y(y^2-y-1)
What is the definition of greatest common factor?
GCF The greatest common factor (or GCF, also HCF, highest common factor) of a group of positive integers is the largest positive integer by which any of the numbers can be divided to yield another integer.To find the GCF, list the factors of each of the numbers in a set, then locate the largest integer that is a factor for all of them. This is the greatest common factor.Here's an example problem : What is the GCF of 24 and 40?The factors of 24 are 1, 2, 3, 4, 6, 8, 12, and 24.The factors of 40 are 1, 2, 4, 5, 8, 10, 20, and 40.The factors common to both are 1, 2, 4, and 8. But the greatest is, of course, 8.There can be no Greatest Common Factor (GCF) for a single number. The Greatest Common Factor (GCF) is the largest factor common to two or more given numbers. You can also see that it is a multiple of every common factor.So rather than list ALL the factors of a number (which could be numerous), the GCF can be discovered as the product of all prime common factors. For example :For the two numbers 168 and 210, the prime factors are found by division.168 = 2 x 2 x 2 x 2 x 3 x 7420 = 2 x 2 x 3 x 5 x 7and the factors they have in common are 2, 2, 3, and 7. Multiplying yields the GCF 84. (We counted 2 twice because it appears twice in each of the numbers.)The GCF is the largest number that divides evenly into each of a given set of numbers.Euclidean AlgorithmIt is not necessary to actually list the factors of all numbers to get the GCF for only two numbers. You can use the Euclidean algorithm.(1) Divide the larger number by the smaller one.(2) If there is no remainder, the GCF is the same as the smaller number.(3) Repeat step 1 with the smaller number and the remainder.Example:GCF of 51 and 85.85/51=1 R 3451/34=1 R 1734/17=2 R 0
How does finding the greatest common factor help us solve real world problems?
That presumes that math class is not part of the real world, which is debatable. Finding the greatest common factor can help reduce fractions. In a practical, non-academic setting, chefs and carpenters work with fractions and might have need of this skill.
When would it be useful to know the common factors or the greatest common factor of two or more numbers?
When you need to reduce fractions to their simplest form.
Where is greatest common factor use?
The greatest common factor is used to reduce fractions.
How do you solve greatest common divisor?
1. Reduce all numbers to prime factors 2. Find primes that are common in all numbers 3. Multiply the common primes together
What is the trick to finding the greatest common factors?
Finding the GCF will help you when you are trying to reduce fractions.
What is two twelfths reduce to?
One sixth.
What do you use greatest common factor for?
To reduce fractions
If you reduce 9 twelfths what would it be?
Three-fourths.
If you reduce 6 twelfths what would it be?
1/2
Why do you have to find the greatest common factor?
It helps to reduce fractions.
