## Determining HCF of Numbers 84,81 by Euclid's Division Lemma

Below detailed show work will make you learn how to find HCF of 84,81 using the Euclidean division algorithm. So, follow the step by step explanation & check the answer for HCF(84,81).

Here 84 is greater than 81

Now, consider the largest number as 'a' from the given number ie., 84 and 81 satisfy Euclid's division lemma statement a = bq + r where 0 ≤ r < b

Step 1: Since 84 > 81, we apply the division lemma to 84 and 81, to get

84 = 81 x 1 + 3

Step 2: Since the reminder 81 ≠ 0, we apply division lemma to 3 and 81, to get

81 = 3 x 27 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 84 and 81 is 3

Notice that 3 = HCF(81,3) = HCF(84,81) .

Therefore, HCF of 84,81 using Euclid's division lemma is 3.
