Mỗi số tự nhiên n khi chia cho 4 có thể có 1 trong các số dư: 0; 1; 2; 3. Do đó mọi số tự nhiên n đều có thể viết được dưới 1 trong 4 dạng: 4k, 4k + 1, 4k + 2, 4k + 3

Với k N*.

- Nếu n = 4k thi n là hợp số.

- Nếu n = 4k + 2 thi n là hợp số.

Vậy mọi số nguyên tố lớn hơn 2 đều có dạng 4k + 1 hoặc 4k +3. Hay mọi số nguyên tố lớn hơn 2 đều có dạng 4n + 1 hoặc 4n +3 với n N*.
