What is 87 mod 3?
Often represented by the operator "mod", the modulo is a mathematical operation that gives the remainder of an integer division.
The result of 87 mod 3 is 0.
How to compute 87 mod 3?
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:
(where N is the dividend, M is the divisor and represents the integer part of the quotient)
- 87 / 3 = 29
- ⌊29⌋ = 29 (We only keep the integer part)
- 3 × 29 = 87
- 87 - 87 = 0 (Subtracting gives us the remainder)
In short: 87 − (3 × ⌊87 / 3⌋) = 0
Is 87 divisible by 3?
A number is said to be divisible by another number, if the remainder of the division is zero.
Given that the result of 87 mod 3 is 0, this indicates that dividing 87 by 3 leaves no remainder. Therefore, yes, 87 is indeed divisible by 3.
