## Determining HCF of Numbers 33,20 by Euclid's Division Lemma

Below detailed show work will make you learn how to find HCF of 33,20 using the Euclidean division algorithm. So, follow the step by step explanation & check the answer for HCF(33,20).

Here 33 is greater than 20

Now, consider the largest number as 'a' from the given number ie., 33 and 20 satisfy Euclid's division lemma statement a = bq + r where 0 ≤ r < b

Step 1: Since 33 > 20, we apply the division lemma to 33 and 20, to get

33 = 20 x 1 + 13

Step 2: Since the reminder 20 ≠ 0, we apply division lemma to 13 and 20, to get

20 = 13 x 1 + 7

Step 3: We consider the new divisor 13 and the new remainder 7, and apply the division lemma to get

13 = 7 x 1 + 6

We consider the new divisor 7 and the new remainder 6,and apply the division lemma to get

7 = 6 x 1 + 1

We consider the new divisor 6 and the new remainder 1,and apply the division lemma to get

6 = 1 x 6 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 33 and 20 is 1

Notice that 1 = HCF(6,1) = HCF(7,6) = HCF(13,7) = HCF(20,13) = HCF(33,20) .

Therefore, HCF of 33,20 using Euclid's division lemma is 1.
