What is 25 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 25 mod 5 is 0.
How to compute 25 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)
- 25 / 5 = 5
- ⌊5⌋ = 5 (We only keep the integer part)
- 5 × 5 = 25
- 25 - 25 = 0 (Subtracting gives us the remainder)
In short: 25 − (5 × ⌊25 / 5⌋) = 0
Is 25 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 25 mod 5 is 0, this indicates that dividing 25 by 5 leaves no remainder. Therefore, yes, 25 is indeed divisible by 5.
