The Highest Common Factor is short is referred to as HCF. Method to find HCF. Trial division is one of the more basic algorithms though it is highly tedious.

It should exactly divide the given numbers. Among the multiple methods to find HCF of two or more numbers prime factorization method is one of them. HCF 2 times 2 times 3 12 Cross any.

Doing the prime factorization of 72 and 48. The factors of 144 and 198 are 1 2 3 4 6 8 9 12 16 18 24 36 48 72 144 and 1 2 3 6 9 11 18 22 33 66 99 198 respectively. HCF of 60 and 72 is 2 2 3 12.

Let us illustrate this with one example. We hence further factorize them with 9 33 and 1535. We can separately find the prime factors of any numbers that are given and then find the HCF by identifying the common factors among them.

Taking the maximum number of distinct factors from each 1 and 2 LCM22233351080. First we have to find the prime factorisation of 60 and 72. H C F 72 48 2 3 3 1 taken the lowest power of prime factors.

Given 72 and 48. Each product contains two 2s and one 3 so use these for the HCF. Now apart from 3 and 5 the other numbers 9 and 15 are composite numbers.

For example 5 divides 35 into 7 hence 5 is a factor of 35 while 7 is also a factor of 35. What are the positive pair factors of 75. Prime factorization of 4 and 9 is 2 2 and 3 3 respectively.

Now the factors of 45 are 135915 and 45 itself. Find the smallest prime number which can divide the given number. One method for finding the prime factors of a composite number is trial division.

So check out the steps to calculate the HCF of given numbers by prime factorization here. Since the common factors of 24 and 36 are 2321 12. Download free printable HCF by Prime Factorisation Method Worksheets to practice.

Answer 1 of 4. Repeat the process until. Then encircle the common factors.

The number itself is also a factor of any number. HCF of 144 and 198. To find the HCF of given numbers we have to find the prime factorisation of each number and then find the HCF.

Lets take a number say 45. One is a factor of every number. It involves testing each integer by dividing the composite number in question by the integer and determining if and how many times the integer can divide the number evenly.

Answer 1 of 3. Let us say that we are interested in finding HCF of 70210315 Let us use prime factorization method to find out HCF 70 275 210 2573 315 5337 Note that 2 is a prime factor of the number 70 and 210 only and it is not a fa. Find the hcf by prime factorization of the numbers 24 and 36.

Then separate the common prime factors of each number and make a list of the common prime factors. To find the HCF find any prime factors that are in common between the products. Free HCF by Prime Factorisation Method Worksheets.

To find the unique prime factorization of any number start dividing it by each prime as many times as possible until the result is one while. We have to find the HCF of 72 and 48 using the prime factorization method. There are 3 commonly used methods to find the HCF of 144 and 198 - prime factorization long division and Euclidean algorithm.

With thousands of questions available you can generate as many HCF by Prime Factorisation Method Worksheets as you want. In Mathematics the Highest Common Factor of two or more numbers is the greatest positive integer x which divides both the given numbers. To find the hcf by prime factorization 24 22231.
