ways to find gcf

ways to find gcf To calculate GCF there are three common ways division multiplication and prime factorization Example Let us find the greatest common factor of 18 and 27 Solution First we list the factors of 18 and 27 and then we find out the common factors Factors of 18 1 2 3 6 9 18 Factors of 27 1 3 9 27

DIRECTIONSs Given each pair of numbers first find the GPGCF Then use the GPGCF to help you find the GCF a 6 10 b 8 12 c 12 15 OK there is also a really easy method we can use the Greatest Common Factor Calculator to find it automatically Other Names The Greatest Common Factor is often abbreviated to GCF and is also known as the Greatest Common Divisor or GCD the Highest Common Factor or HCF

The greatest common divisor GCD and greatest common factor GCF are the same thing To find the GCD GCF of two numbers list their factors identify the common factors and choose the largest one For example the GCD GCF of 12 and 8 is 4 Numbers with a GCD GCF of 1 are called relatively prime Created by Sal Khan There are various methods that help you to find GCF Some of them are child s play while others are more complex It s worth knowing all of them so you can decide which you prefer Using the list of factors Prime factorization of numbers Euclidean algorithm Binary algorithm Stein s algorithm and

Step 1 List or write ALL the factors of each number Step 2 Identify the common factors You can do that by encircling each common factor or drawing a line segment between them It s really up to you how you want to mark the common factors so they stand out One way to find the GCF of two or more numbers is to list the factors of each number and find the greatest factor they have in common Want to learn more about greatest common factors Check out this video Example GCF of 12 and 18 Factors of 12 1 2 3 4 6 12 Factors of 18 1 2 3 6 9 18

One way to find a GCF is to make a list of the factors of each number Then look at each list and find the largest number that they have in common For example let s look at how to find the GCF of 12 and 18 First start by making a Google Classroom About Transcript The greatest common factor GCF of a set of numbers is the largest factor that all the numbers share For example 12 20 and 24 have two common factors 2 and 4 The largest is 4 so we say that the GCF of 12 20 and 24 is 4 GCF is often used to find common denominators Created by Sal Khan Questions

Answer GCF 4 Greatest Common Factor for the values 8 12 20 Solution by Factorization The factors of 8 are 1 2 4 8 The factors of 12 are 1 2 3 4 6 12 The factors of 20 are 1 2 4 5 10 20 Then the greatest common factor is 4 You can also find the GCF using Prime Factorization or Euclid s Algorithm If there are no common prime factors the greatest common factor is 1 Finding the GCF of a given number set can be easy However there are several steps need to be followed to get the correct GCF
