how do you find the highest common factor To find the greatest common factor of two or more numbers make a list of all of the factors of each number For example for the number 10 the factors are 1 2 5 and 10 and for the number 21 the factors are 1 3 7 and 21
For example 8 and 12 have common factors of 1 2 and 4 The highest common factor is 4 Answer To determine the required number the highest common factor of 136 64 238 136 and 238 64 that is the HCF 72 102 174 needs to be found 72 2 3 3 2 102 2 3 17 174 2 3 29 HCF 72 102 174 2 3 6 6 is the required number

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 So the largest number we can divide both 12 and 30 exactly by is 6 like this The Greatest Common Factor of 12 and 30 is 6 And so 12 30 can be simplified to 2 5 How to find the highest common factor In order to calculate the highest common factor for two or more numbers State the product of prime factors for each number not in index form you can work these out using a prime factor tree Write all the prime factors into the Venn diagram for each number
Highest Common Factor of two or more numbers is the greatest possible number that divides the given numbers evenly Highest common factor of two consecutive numbers is 1 Learn the methods to find HCF at BYJU S Eg 10 is the highest common factor of 30 and 20 Highest common factor is written as HCF HCF is the greatest factor that will divide into two or more numbers

24 2 2 2 3 To find the HCF multiply the numbers that are in common to both lists 2 2 2 8 and so 8 is the highest common factor of 16 and 24 Make a list of all of the factors for each number The highest common factor is the largest number in common to all of the lists GCF which stands for Greatest common factor is the largest value of the values you have that multiplied by whole number is able to step onto both For example the GCF of 27 and 30 is 3 since if you add 3 repeatedly it will equal 27 after it is added 9 times and equal 30 after adding 3 10 times
