What is 19 mod 1?

How to compute 19 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. 19 / 1 = 19
2. ⌊19⌋ = 19 (We only keep the integer part)
3. 1 × 19 = 19
4. 19 - 19 = 0 (Subtracting gives us the remainder)

In short: 19 − (1 × ⌊19 / 1⌋) = 0

Is 19 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 19 mod 1 is 0, this indicates that dividing 19 by 1 leaves no remainder. Therefore, yes, 19 is indeed divisible by 1.
