a= bq + r, where 0 ≤ r < b
2. Euclid’s Division Algorithm: To find the HCF of two positive integers a and b where a > b, you have to consider the following steps.
Step 1: Use division lemma to find the values of q and r (a= bq + r, where 0 ≤ r < b).
Step 2: HCF of a and b = b, if r = 0. In case, r ≠ 0 then apply Euclid’s lemma to b and r.
Step 3: Follow the process until the remainder is zero. Take divisor as HCF (a, b). Also, HCF (a, b) = HCF (b,r)
