GCF Calculator GCF of 84 and 57 Copyright | Privacy Policy | Disclaimer | Contact The first step to this method of finding the Greatest Common Factor of 56 and 84 is to find and list all the factors of each number. Again, you can see how this is done by looking at the “Factors of” articles that are linked to above. Let’s take a look at the factors for each of these numbers, 56 and 84: Factors of 56: 1, 2, 4, 7, 8, 14, 28, 56 Factors of 84: 1, 2, 3, 4, 6, 7, 12, 14, 21, 28, 42, 84 When you compare the two lists of factors, you can see that the common factor(s) are 1, 2, 4, 7, 14, 28. Since 28 is the largest of these common factors, the GCF of 56 and 84 would be 28. The first step to this method of finding the Greatest Common Factor of 84 and 56 is to find and list all the factors of each number. Again, you can see how this is done by looking at the “Factors of” articles that are linked to above. Let’s take a look at the factors for each of these numbers, 84 and 56: Factors of 84: 1, 2, 3, 4, 6, 7, 12, 14, 21, 28, 42, 84 Factors of 56: 1, 2, 4, 7, 8, 14, 28, 56 When you compare the two lists of factors, you can see that the common factor(s) are 1, 2, 4, 7, 14, 28. Since 28 is the largest of these common factors, the GCF of 84 and 56 would be 28. Are you on the hunt for the GCF of 56 and 84? Since you're on this page I'd guess so! In this quick guide, we'll walk you through how to calculate the greatest common factor for any numbers you need to check. Let's jump in! Want to quickly learn or show students how to find the GCF of two or more numbers? Play this very quick and fun video now! First off, if you're in a rush, here's the answer to the question "what is the GCF of 56 and 84?": GCF of 56 and 84 = 28 What is the Greatest Common Factor?Put simply, the GCF of a set of whole numbers is the largest positive integer (i.e whole number and not a decimal) that divides evenly into all of the numbers in the set. It's also commonly known as:
There are a number of different ways to calculate the GCF of a set of numbers depending how many numbers you have and how large they are. For smaller numbers you can simply look at the factors or multiples for each number and find the greatest common multiple of them. For 56 and 84 those factors look like this:
As you can see when you list out the factors of each number, 28 is the greatest number that 56 and 84 divides into. Prime FactorsAs the numbers get larger, or you want to compare multiple numbers at the same time to find the GCF, you can see how listing out all of the factors would become too much. To fix this, you can use prime factors. List out all of the prime factors for each number:
Now that we have the list of prime factors, we need to find any which are common for each number. Looking at the occurences of common prime factors in 56 and 84 we can see that the commonly occuring prime factors are 2, 2, and 7. To calculate the prime factor, we multiply these numbers together: GCF = 2 x 2 x 7 = 28 Find the GCF Using Euclid's AlgorithmThe final method for calculating the GCF of 56 and 84 is to use Euclid's algorithm. This is a more complicated way of calculating the greatest common factor and is really only used by GCD calculators. If you want to learn more about the algorithm and perhaps try it yourself, take a look at the Wikipedia page. Hopefully you've learned a little math today and understand how to calculate the GCD of numbers. Grab a pencil and paper and give it a try for yourself. (or just use our GCD calculator - we won't tell anyone!)
