Phương pháp giải:Ta có thể giải bài toán bằng cách sử dụng sự phân tích thừa số nguyên tố của 2940 và 210, sau đó tìm ra 2 số a và b thỏa mãn yêu cầu của bài toán.Phân tích thừa số nguyên tố của 2940 và 210:2940 = 2^2 * 3 * 5 * 7 * 7210 = 2 * 3 * 5 * 7Suy ra, 2940 = 2^2 * 3 * 5 * 7 * 7 = 2^2 * 3 * 5 * 7^2, và BCNN của 2940 và 210 là 2^2 * 3 * 5 * 7^2.Do đó, ta có a = 2^2 * 3 = 12 và b = 5 * 7^2 = 245.Vậy, 2 số tự nhiên a và b cần tìm là 12 và 245.
