What is 23 mod 1?

How to compute 23 mod 1?

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:

$\mathrm{Remainder}=N-(M\times \lfloor \frac{N}{M}\rfloor )$

(where N is the dividend, M is the divisor and $\lfloor \frac{N}{M}\rfloor$ represents the integer part of the quotient)

1. 23 / 1 = 23
2. ⌊23⌋ = 23 (We only keep the integer part)
3. 1 × 23 = 23
4. 23 - 23 = 0 (Subtracting gives us the remainder)

In short: 23 − (1 × ⌊23 / 1⌋) = 0

Is 23 divisible by 1?

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

Given that the result of 23 mod 1 is 0, this indicates that dividing 23 by 1 leaves no remainder. Therefore, yes, 23 is indeed divisible by 1.
