Want to know how to use Euclid’s algorithm to find the HCF of 65, 143, 169 ? Well, you have come to the right place. In this article, you will be learning about Euclid’s algorithm and how to use it to calculate the HCF with ease.
Take the help of the HCF Calculator using the Euclid Division Algorithm which finds HCF of 65, 143, 169 using Euclid's algorithm i.e 13 quickly.

Detailed Method to Find the HCF of 65,143,169 using Euclid's algorithm

Euclid’s algorithm is written as a = bq + r. This is known as the division lemma. The variable r varies according to 0 ≤ r ≤ b. We can use this to figure out the HCF of 65,143,169. This is how to do it.

Step 1: The first step is to use the division lemma with 143 and 65 because 143 is greater than 65

143 = 65 x 2 + 13

Step 2: Here, the reminder 65 is not 0, we must use division lemma to 13 and 65, to get

65 = 13 x 5 + 0

As you can see, the remainder is zero, so you may end the process at this point. From the last equation, we can determine that the divisor is 13.Therefore, the HCF of 65 and 143 is equal to 13

Notice that 13 = HCF(65,13) = HCF(143,65) .

Now, we must treat the HCF of the first two numbers as the next number in our calculation, and next

Step 1: The first step is to use the division lemma with 169 and 13 because 169 is greater than 13

169 = 13 x 13 + 0

As you can see, the remainder is zero, so you may end the process at this point. From the last equation, we can determine that the divisor is 13.Therefore, the HCF of 13 and 169 is equal to 13

Notice that 13 = HCF(169,13) .

Result

Hence, the HCF of 65, 143, 169 is equal to 13.
