Ý tưởng là thử chia số và xem kết quả có phải là số nguyên không. Tuy nhiên, tôi không nhận được kết quả như mong đợi
Làm cách nào để kiểm tra xem số đó có phải là số nguyên không?
Trong 2. x, phép chia như thế này sẽ tạo ra một số nguyên, loại bỏ phần dư;
Trong 3. x, phép chia sẽ tạo ra một giá trị dấu phẩy động; . Xem Tại sao phép chia số nguyên mang lại số float thay vì số nguyên khác?
Nếu bạn cần phần còn lại từ phép chia số nguyên thay vì chỉ kiểm tra tính chia hết, hãy xem Tìm phần còn lại của phép chia của một số
Cho một số, nhiệm vụ là kiểm tra xem số đó có chia hết cho 5 không. Số đầu vào có thể lớn và không thể lưu trữ ngay cả khi chúng ta sử dụng long long int
ví dụ.
Input : n = 56945255 Output : Yes Input : n = 1234567589333150 Output : Yes Input : n = 3635883959606670431112222 Output : No
Đề nghị thực hành
Kiểm tra xem có chia hết cho 5 không
Thử nó
Vì số đầu vào có thể rất lớn, chúng tôi không thể sử dụng n % 5 để kiểm tra xem một số có chia hết cho 5 hay không, đặc biệt là trong các ngôn ngữ như C/C++. Ý tưởng dựa trên thực tế sau đây.
A number is divisible by 5 if its digits last digit will be 0 or 5 .
Hình minh họa.
For example, let us consider 769555 Number formed by last digit is = 5 Since 5 is divisible by 5 , answer is YES.
Cái này hoạt động ra sao?
Let us consider 5335, we can write it as 5335 = 5*1000 + 3*100 + 3*10 + 5 The proof is based on below observation: Remainder of 10i divided by 5 is 0 if i greater than or equal to one. Note than 10, 100, 1000, .. etc lead to remainder 0 when divided by 5. So remainder of " 5*1000 + 3*100 + 3*10 + 5" divided by 5 is equivalent to remainder of following : 0 + 0 + 0 + 5 = 5 Since 5 is divisible by 5, answer is yes.

Làm cách nào để kiểm tra xem một số có chia hết cho cả 5 và 7 trong Python không?
Python3. nếu cnt % 7 = = 0 và cnt % 5 = = 0. print [cnt, " chia hết cho 7 và 5. " ]
Số nào chia hết cho 5 và 11?
Nhập số. 55 55 chia hết cho 5 và 11.
Cái gì chia hết cho 11 trong Python?
Kiểm tra tính chia hết cho 11 trạng thái nếu hiệu giữa tổng các chữ số lẻ và tổng các chữ số chẵn trong một số chia hết cho 11 thì số đó gọi là . Ví dụ: 7689, theo đó tổng các chữ số lẻ = 9 + 6 = 15, tổng các chữ số chẵn = 8 + 7 = 15. . For example, 7689, whereby the sum of odd digits = 9 + 6 = 15, while sum of even digits = 8 + 7 = 15.
