What is 4 mod 2?
Often represented by the operator "mod", the modulo is a mathematical operation that gives the remainder of an integer division.
The result of 4 mod 2 is 0.
How to compute 4 mod 2?
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)
- 4 / 2 = 2
- ⌊2⌋ = 2 (We only keep the integer part)
- 2 × 2 = 4
- 4 - 4 = 0 (Subtracting gives us the remainder)
In short: 4 − (2 × ⌊4 / 2⌋) = 0
Is 4 divisible by 2?
A number is said to be divisible by another number, if the remainder of the division is zero.
Given that the result of 4 mod 2 is 0, this indicates that dividing 4 by 2 leaves no remainder. Therefore, yes, 4 is indeed divisible by 2.
