Among any four consecutive integers, one is divisible by 4.

Sever: Among Any Four Consecutive Integers, One Is Always Divisible by 4

In the world of number theory and fundamental properties of integers, a fascinating and universally true pattern emerges: among any four consecutive integers, one is always divisible by 4. This elegant mathematical truth holds regardless of the starting point and offers a simple yet powerful example of structure within the infinite set of whole numbers.

Why Does This Happens?

Understanding the Context

Four consecutive integers can be expressed as:
n, n+1, n+2, n+3, where n is any integer.

Let’s analyze their divisibility by 4 based on modular arithmetic.

Every integer, when divided by 4, leaves a remainder of 0, 1, 2, or 3. So, for any four consecutive numbers, their remainders modulo 4 are exactly one full cycle: 0, 1, 2, 3 — in some order.

Mathematically, the possible remainders cover all values from 0 to 3, meaning one of the four numbers must give a remainder of 0 when divided by 4 — that is, it is divisible by 4.

Among any four consecutive integers, one is divisible by 4.

Examples to Illustrate the Rule

Example 1: 5, 6, 7, 8
Here, 8 is divisible by 4.
Example 2: –3, –2, –1, 0
Among these, 0 is divisible by 4.
Example 3: 10, 11, 12, 13
Here, 12 is divisible by 4.

No matter which four consecutive numbers you pick — positive, negative, or zero — one will always be a multiple of 4.
