HCF full form is the Highest Common Factor. But, are you aware of the process used in finding HCF of a number in Mathematics? Don’t worry. Read the article below to know the details regarding HCF full form, methods to find HCF of a given number and a lot more.
HCF full form is the Highest Common Factor. The highest factor or the number that divides any pair of two or more numbers evenly is known as the HCF or highest common factor. The Greatest Common Measure (GCM) and the Greatest Common Divisor (GCD) are other names used for HCF. HCF can be accessible by using two or more numbers. For each pair of integers that can evenly or completely divide the given numbers, it is the most efficient divisor. For example, 12 is the greatest number that can divide 24 and 60 completely, making it the highest common factor of these two numbers. We can find the HCF of any given numbers by using two specific methods: The methods and details of two methods are discussed below: To find the HCF of any given numbers using the prime factorisation method, follow the steps below: Examples of HCF Example 1: Find the HCF of 60 and 75 Solution: Write each number as a product of its prime factors. 22 x 3 x 5 = 60 3 x 52 = 75 The product of all common prime factors is known as the HCF The common prime factors in this example are 3 and 5 The lowest power of 3 is 3 and 5 is 5 Therefore, the HCF = 3 x 5 = 15 Example 2: Find the HCF of 36, 24 and 12 Solution: Each number with its prime factors are- 22 x 32 = 36 23 x 3 = 24 22 x 3 = 12 As we know, the product of all common prime factors is the HCF ( use the lowest power of each common factor) The common prime factors in this example are 2 and 3 The lowest power of 2 is 22 and 3 is 3 So, the HCF is 22 x 3 = 12 Example 3: Find the HCF of 36, 27 and 80. Solution: Write each number as a product of its prime factors 22 x 32 = 36 33 = 27 24 x 5 = 80 The product of all common prime factors is called HCF The common prime factors in this example are none So the HCF is 1 One of the most important methods of finding the highest common factor (HCF) is by prime factorization method. HCF can also be found by another method known as the ‘division method’. Basically, the division method is nothing but dividing the given numbers, at the same time to get the common factors between them. Following are the steps mentioned to solve the problems of HCF using the division method: Let us understand the above-mentioned steps to find the HCF by ‘division method’ with the help of examples below Example 1: Evaluate the HCF of 30 and 75 The above mentioned prime factors on the left side, divide all the numbers completely. Therefore, they are considered as common prime factors. For the numbers remaining at the bottom, there is no common prime factor. Therefore, the HCF is, 3 × 5 = 15 Example 2: Find out HCF of 36 and 24 HCF = 2 × 2 × 3 = 12 Example 3: Find out HCF of 36, 12, 24 and 48 So, the HCF is 2 × 2 × 3 = 12 Steps to find the HCF of any given set of numbers using the shortcut method are: Larger Number/Smaller Number Find the steps to calculate the HCF of the 3 numbers and the rest of the steps are given below: 1) Calculate the HCF of 2 numbers 2) Then Find the HCF of the 3rd number and the HCF found in step 1 3) The HCF you received in step 2 will be the HCF of the 3 numbers Moreover, the above steps can also be used to find the HCF of more than 3 numbers. The simple and easy steps to find the HCF of 4 numbers are given below: The major properties of HCF are given below:What is HCF Full Form?

What are the Major Properties of HCF?
The HCF full form is the Highest Common Factor.
HCF means the Highest Common Factor. While finding the factors of two or more numbers some numbers are found to be common. The greatest factor found from the common factors is called the HCF in Mathematics.
The HCF is calculated by:
The HCF can be evaluated for two or more numbers.
The other terms used for HCF are: Greatest Common Factor (GCF) or Greatest Common Divisor (GCD).
