Make use of the HCF Calculator provided here and calculate the highest common factor for the given numbers. Just enter your numbers in the below input box and then click on the Calculate button to get the accurate HCF Solution for the entered integers.
Here are some samples of HCF Numbers calculations.
HCF Calculator: Finding the Highest Common Factor is similar to the Greatest common factor or divisor as HCF is also known as GCF or GCD. You can calculate HCF of given numbers easily by approaching the standard methods manually. If you want to make your calculation of the Highest common factor effortlessly & quickly then using the HCF Calculator is the best option. By just taking the given inputs, the HCF Calculator provides the largest integer in a split second. Also, it gives detailed procedures along with show work.
The largest common factor that divides the given set of numbers exactly with zero remainders is known as the Highest Common Factor(HCF). HCF also is known as GCF and GCD. For two integers ie., a, b the HCF is indicated as HCF(a,b).
For example, if you take two numbers ie., 54 and 60 then the Highest Common Factor of numbers is the 6 ie., the largest integer that exactly divided the two numbers with zero remainders. Therefore, HCF(54, 60) is 6.
Procedure to Find the Highest Common Factor of Given Numbers
For a better understanding of the HCF of numbers, we are giving manual procedures on how to calculate the HCF of given numbers with different methods. There are so many methods to find out the Highest common factor of numbers but major methods that everyone should be aware of are providing here in a detailed way. They are as follows:
HCF of Given Numbers By Factoring
By using the Factoring method, we can easily find the HCF of numbers. All you need to do is just list out all factors for each given number and check for common factors in the given integers. Thereafter, consider the largest common factor from the list of common factors you found as the Highest Common factor of given numbers.
Look detailed steps of finding the HCF of Numbers using a list of factors method from the below given solved example and understand the method efficiently.
Find the HCF of 60 and 40 using the factoring method?
Given number are 60 and 40
Now, we are finding the HCF(60, 40) by factoring
At the First Step, you need to list out the factors of 60 and 40
Factors of 60
List of all factors of 60 that divides with zero remainder are 1,2,3,4,5,6,10,12,15,20,30,60
Factors of 40
List of all factors of 40 that divides with zero remainder are 1,2,4,5,8,10,20,40
At the Second Step, need to separate the common factors from the given number factors list and find the largest integer
1, 2, 4, 5, 10, 20.
The bolded number is the largest common factor of both integers so it can be considered as the highest common factor of 60 and 40.
Therefore, HCF of 60 & 40 is 20.
If your given numbers are big to solve then prime factorization is the best method compared to factoring. So, check out the steps to calculate the HCF of given numbers by prime factorization here:
Let's check the closer look of finding the HCF of numbers by Prime factorization with the help of show work given below.
Find the Highest common factor of 40 and 60 by prime factorization?
Given numbers are 40 and 60,
Now, we have to find HCF(40, 60) using Prime factorization
Step 1: Find the prime factors for 40 and 60,
The prime factorization of 40 is 2 x 5.
The prime factorization of 60 is 2 x 3 x 5.
Step 2: List out the highest number of common prime factors of 40 and 60 ie.,
2 x 2 x 5
Step 3: Now, on multiplying the common prime factors we will get the HCF of two numbers
2 * 2 * 5 = 40
Thus, the Highest Common Factor of 40 and 60 is 20.
Highest Common Factor of Numbers by Division Method
The procedure to find the HCF of number by division method is as follows:
Find the HCF of 30 and 42 using the Division method?
Given numbers are 30 and 42
For finding the HCF of given numbers by division method, you need to take a large number i.e., 42 as dividend and a small number ie., 30 as a divisor.
Now, divide 42 by 30 and get the HCF of 30 and 42 by performing the division method.
When you get the remainder zero then that divisor i.e., 6 is the HCF of given numbers.
Thus, HCF of 30 and 42 is 6.
