What is 3 mod 69?

How to compute 3 mod 69?

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. 3 / 69 = 0.043478260869565
2. ⌊0.043478260869565⌋ = 0 (We only keep the integer part)
3. 69 × 0 = 0
4. 3 - 0 = 3 (Subtracting gives us the remainder)

In short: 3 − (69 × ⌊3 / 69⌋) = 3

Is 3 divisible by 69?

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

Given that the result of 3 mod 69 is 3, this indicates that dividing 3 by 69 leaves a remainder of 3. Therefore, no, since the remainder isn't zero, 3 is not divisible by 69.
