## Determining HCF of Numbers 51,66 by Euclid's Division Lemma

Below detailed show work will make you learn how to find HCF of 51,66 using the Euclidean division algorithm. So, follow the step by step explanation & check the answer for HCF(51,66).

Here 66 is greater than 51

Now, consider the largest number as 'a' from the given number ie., 66 and 51 satisfy Euclid's division lemma statement a = bq + r where 0 ≤ r < b

Step 1: Since 66 > 51, we apply the division lemma to 66 and 51, to get

66 = 51 x 1 + 15

Step 2: Since the reminder 51 ≠ 0, we apply division lemma to 15 and 51, to get

51 = 15 x 3 + 6

Step 3: We consider the new divisor 15 and the new remainder 6, and apply the division lemma to get

15 = 6 x 2 + 3

We consider the new divisor 6 and the new remainder 3, and apply the division lemma to get

6 = 3 x 2 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 51 and 66 is 3

Notice that 3 = HCF(6,3) = HCF(15,6) = HCF(51,15) = HCF(66,51) .

Therefore, HCF of 51,66 using Euclid's division lemma is 3.
