What is 83 mod 4?

Often represented by the operator "mod", the modulo is a mathematical operation that gives the remainder of an integer division.

The result of 83 mod 4 is 3.

How to compute 83 mod 4?

The simplest approach is to use the "mod" operator (often denoted as "%" in many programming languages), but you could do it manually in the following way:

Remainder = N − ( M × ⌊ N M ⌋ )

(where N is the dividend, M is the divisor and ⌊ N M ⌋ represents the integer part of the quotient)

  1. 83 / 4 = 20.75
  2. ⌊20.75⌋ = 20 (We only keep the integer part)
  3. 4 × 20 = 80
  4. 83 - 80 = 3 (Subtracting gives us the remainder)

In short: 83 − (4 × ⌊83 / 4⌋) = 3

Is 83 divisible by 4?

A number is said to be divisible by another number, if the remainder of the division is zero.

Given that the result of 83 mod 4 is 3, this indicates that dividing 83 by 4 leaves a remainder of 3. Therefore, no, since the remainder isn't zero, 83 is not divisible by 4.
