What is 42 mod 1?

How to compute 42 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. 42 / 1 = 42
2. ⌊42⌋ = 42 (We only keep the integer part)
3. 1 × 42 = 42
4. 42 - 42 = 0 (Subtracting gives us the remainder)

In short: 42 − (1 × ⌊42 / 1⌋) = 0

Is 42 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 42 mod 1 is 0, this indicates that dividing 42 by 1 leaves no remainder. Therefore, yes, 42 is indeed divisible by 1.
