C# How to determine if a number is a multiple of another?

Try

public bool IsDivisible(int x, int n)
{
   return (x % n) == 0;
}

The modulus operator % returns the remainder after dividing x by n which will always be 0 if x is divisible by n.

For more information, see the % operator on MSDN.

bool isMultiple = a % b == 0;

This will be true if a is a multiple of b

Use the modulus (%) operator:

6 % 3 == 0
7 % 3 == 1
