Cách tìm lcm và hcf của hai số trong python

LCM [Bội chung nhỏ nhất] của hai số là số nhỏ nhất chia hết cho cả hai số.  

Ví dụ: LCM của 15 và 20 là 60 và LCM của 5 và 7 là 35

Một giải pháp đơn giản là tìm tất cả các thừa số nguyên tố của cả hai số, sau đó tìm hợp của tất cả các thừa số có trong cả hai số. Cuối cùng, trả về sản phẩm của các yếu tố trong hiệp hội

Một giải pháp hiệu quả dựa trên công thức dưới đây cho LCM của hai số 'a' và 'b'.  

   a x b = LCM[a, b] * GCD [a, b]

   LCM[a, b] = [a x b] / GCD[a, b]

Chúng ta đã thảo luận về chức năng tìm GCD của hai số. Sử dụng GCD, chúng ta có thể tìm thấy LCM.  

Dưới đây là triển khai ý tưởng trên
