Take the help of the HCF Calculator using the Euclid Division Algorithm which finds HCF of 8, 28, 36 using Euclid's algorithm i.e 4 quickly.

Detailed Method to Find the HCF of 8,28,36 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 8,28,36. This is how to do it.

Step 1: The first step is to use the division lemma with 28 and 8 because 28 is greater than 8

28 = 8 x 3 + 4

Step 2: Here, the reminder 8 is not 0, we must use division lemma to 4 and 8, to get

8 = 4 x 2 + 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 4.Therefore, the HCF of 8 and 28 is equal to 4

Notice that 4 = HCF(8,4) = HCF(28,8) .

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 36 and 4 because 36 is greater than 4

36 = 4 x 9 + 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 4.Therefore, the HCF of 4 and 36 is equal to 4

Notice that 4 = HCF(36,4) .

Result

Hence, the HCF of 8, 28, 36 is equal to 4.
