What is 43 mod 1?

How to compute 43 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. 43 / 1 = 43
2. ⌊43⌋ = 43 (We only keep the integer part)
3. 1 × 43 = 43
4. 43 - 43 = 0 (Subtracting gives us the remainder)

In short: 43 − (1 × ⌊43 / 1⌋) = 0

Is 43 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 43 mod 1 is 0, this indicates that dividing 43 by 1 leaves no remainder. Therefore, yes, 43 is indeed divisible by 1.
