Want to know how to use Euclid’s algorithm to find the HCF of 36, 48, 72 ? 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 36, 48, 72 using Euclid's algorithm i.e 12 quickly.

Detailed Method to Find the HCF of 36,48,72 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 36,48,72. This is how to do it.

Step 1: The first step is to use the division lemma with 48 and 36 because 48 is greater than 36

48 = 36 x 1 + 12

Step 2: Here, the reminder 36 is not 0, we must use division lemma to 12 and 36, to get

36 = 12 x 3 + 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 12.Therefore, the HCF of 36 and 48 is equal to 12

Notice that 12 = HCF(36,12) = HCF(48,36) .

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 72 and 12 because 72 is greater than 12

72 = 12 x 6 + 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 12.Therefore, the HCF of 12 and 72 is equal to 12

Notice that 12 = HCF(72,12) .

Result

Hence, the HCF of 36, 48, 72 is equal to 12.
