What is 15 mod 9?
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 9 is 6.
How to compute 15 mod 9?
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 / 9 = 1.6666666666667
- ⌊1.6666666666667⌋ = 1 (We only keep the integer part)
- 9 × 1 = 9
- 15 - 9 = 6 (Subtracting gives us the remainder)
In short: 15 − (9 × ⌊15 / 9⌋) = 6
Is 15 divisible by 9?
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 9 is 6, this indicates that dividing 15 by 9 leaves a remainder of 6. Therefore, no, since the remainder isn't zero, 15 is not divisible by 9.
