Determining HCF of Numbers 646,63 by Euclid's Division Lemma

Below detailed show work will make you learn how to find HCF of 646,63 using the Euclidean division algorithm. So, follow the step by step explanation & check the answer for HCF(646,63).

Here 646 is greater than 63

Now, consider the largest number as 'a' from the given number ie., 646 and 63 satisfy Euclid's division lemma statement a = bq + r where 0 ≤ r < b

Step 1: Since 646 > 63, we apply the division lemma to 646 and 63, to get

646 = 63 x 10 + 16

Step 2: Since the reminder 63 ≠ 0, we apply division lemma to 16 and 63, to get

63 = 16 x 3 + 15

Step 3: We consider the new divisor 16 and the new remainder 15, and apply the division lemma to get

16 = 15 x 1 + 1

We consider the new divisor 15 and the new remainder 1, and apply the division lemma to get

15 = 1 x 15 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 646 and 63 is 1

Notice that 1 = HCF(15,1) = HCF(16,15) = HCF(63,16) = HCF(646,63) .

Therefore, HCF of 646,63 using Euclid's division lemma is 1.
