What is 53 mod 3?

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

The result of 53 mod 3 is 2.

How to compute 53 mod 3?

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. 53 / 3 = 17.666666666667
  2. ⌊17.666666666667⌋ = 17 (We only keep the integer part)
  3. 3 × 17 = 51
  4. 53 - 51 = 2 (Subtracting gives us the remainder)

In short: 53 − (3 × ⌊53 / 3⌋) = 2

Is 53 divisible by 3?

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

Given that the result of 53 mod 3 is 2, this indicates that dividing 53 by 3 leaves a remainder of 2. Therefore, no, since the remainder isn't zero, 53 is not divisible by 3.
