E Euclidean Algorithm
omes 12, q = 1, r = 6) 3. 12 = 6 × 2 + 0 (Finally, a becomes 12, b becomes 6, q = 2, r = 0) Since the remainder is 0, the GCD is the last non-zero remainder, which is 6. Therefore, the GCD(48, 18) = 6. 4. Variations and Optimizations While the basic iterative approach is effective, variati
