The Highest Common Factor is particularly significant in basic arithmetic, especially in procedures that require both multiplication and division. Let’s take a closer look at the fundamentals that underpin the entire HCF concept.

What exactly is HCF?

The HCF of any two or more natural numbers supplied is the biggest or largest factor common to those two or more numbers. GCD (Greatest Common Divisor), the greatest common denominator (GCD), and the greatest common divisor (GCD) are all terminologies that are used to express HCF.

Learning about factors and multiples will help you find HCF (Highest Common Factor) and LCM (Lowest Common Multiple) (Least Common Multiple).


What are the multipliers and factors?


When we talk about any number factor, we’re talking about any number that divides a particular number completely, leaving no residue. For example, the explanations for 27 are 1, 3, 9, and 27. The number 4 cannot divide 10 without leaving a leftover. When we divide the number 10 by 4, the result is clearly 2.5, which does not come under the category of integer numbers. As a result, 4 cannot be considered a factor of ten. It’s important to notice that the variables are either less than or equal to the original value.


When you talked about multiples, on the other hand, you were actually practicing multiples. The counting tables you learned in primary school, such as 2, 4, 6, 8, and 10, 12, are all multiples of two. To acquire these numbers, you multiplied 2 by 1, 2, 3, 4, and 5, all of which are integers.


How do I locate HCF?


Now that you understand what multiples and variables are, we’ll move on to the formal notion of HCF and gain a greater understanding of it.


Finding the integers’ Highest Common Factors is a simple and straightforward procedure. In general, there are two major ways for determining the HCF (Highest Common Factor) of numbers that everyone finds simple. The Prime Factorization Method and the Division Method are the two methods.


Method of Factorization:


The method for determining the highest common factor is straightforward. This method of factorization entails converting all of the variables/divisors into two or more numbers. When listing the divisors of a certain number, the most important item to remember is the largest or highest number, which usually divides the numbers without leaving any residue.


Example that has been solved


Q.1) Using the factorization method, calculate the HCF of 16 and 32.




The factors of the number 16 are 1, 2, 3, 4, 6, 8, and the number itself.


((1 16, 2 8, 3 6, 4 4)))))))))))))))))))))))))))))))


The components of 32 are 1, 2, 4, 6, 8, 16, and 32itself, as we know. 1 32, 2 16, 4 8, 8x 8x 8x 8x 8x 8x 8x 8x 8x 8x 8x 8x 8x 8x 8x 8x


As a result, it is evident that the highest or biggest factor in terms of the value of both the numbers 16 and 32 is 8, and so the HCF of 16 and 32 is 8.


Method of prime factorization:


Another essential and straightforward method includes the use of two or more numbers as prime factor products. We go on to describe the fundamental variables, which are similar to the numbers mentioned. The common prime variable is the result of this procedure, which is the Highest Common Factor or Greatest Common Divisor of the numbers.


Example that has been solved:


Q.2) Using the prime factorization method, calculate the HCF of 16 and 32.


Solution: We begin this procedure by determining the prime elements individually.


The prime factors of 16 are 2 x 2 x 2 x 2 x 2 x 2 x 2 x 2 x 2 x 2 x 2


2 x 2 x 3 x 3 prime factors


By prime factorization, the HCF of 16 and 32 is 2 x 2 = 4.


manner of division


Another good way for discovering or computing the HCF is to divide it. It’s useful in situations where you need to calculate the HCF of two numbers.


You must determine the greater and smaller numbers in those two specified figures. Then divide the larger number into smaller ones, and then divide the divider by the reminder. And this is how you should go about executing the division technique till you get a zero-result.


When discussing alternative methods for calculating HCF, it’s important to remember that there are several other methods for determining the greatest or highest common number factor. Aside from the physical methods mentioned above, using an online calculator is the most dependable, quick, and simple method you may employ.


Calculator for HCF and GCF


The GCF Calculator is essentially an internet tool that anyone can use to find HCF issues more quickly. Because there are many calculators on the internet that give their services for free, one of the most well-known is the meracalculator website, which offers students the HCF calculator to answer mathematical issues. It is without a doubt one of the website’s most effective and handy calculators. Of course, it will spare you from tedious algebraic computations and manipulations.


It’s also known as the HCF-finder or HCF-calculator because it can identify HCF in a matter of seconds. The calculator’s best feature is that it can calculate the greatest common factor of a list of numbers ranging from two to infinite in a fraction of the time. Using an online calculator is the simplest and fastest approach to compute HCF among the ways we described earlier.
