What is 15 mod 5?
Often represented by the operator "mod", the modulo is a mathematical operation that gives the remainder of an integer division.
The result of 15 mod 5 is 0.
How to compute 15 mod 5?
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)
- 15 / 5 = 3
- ⌊3⌋ = 3 (We only keep the integer part)
- 5 × 3 = 15
- 15 - 15 = 0 (Subtracting gives us the remainder)
In short: 15 − (5 × ⌊15 / 5⌋) = 0
Is 15 divisible by 5?
A number is said to be divisible by another number, if the remainder of the division is zero.
Given that the result of 15 mod 5 is 0, this indicates that dividing 15 by 5 leaves no remainder. Therefore, yes, 15 is indeed divisible by 5.
