Numbers we can multiply together to get another number.
Example: 2 and 3 are factors of 6, because 2 × 3 = 6
A number can have MANY factors!
Example: What are the factors of 12?
• 3 × 4 = 12, so 3 and 4 are factors of 12
• 2 × 6 = 12, so 2 and 6 are also factors of 12
• and 1 × 12 = 12, so 1 and 12 are factors of 12 as well
So 1, 2, 3, 4, 6 and 12 are all factors of 12
And -1, -2, -3, -4, -6 and -12 also, because multiplying negatives makes a positive.
using System; namespace Program { class Program { static void Main(string[] args) { int num, x; Console.WriteLine("Enter the Number: "); num = Convert.ToInt16(Console.ReadLine()); Console.WriteLine("\nThe Factors are: "); for (x = 1; x <= num; x++) { if (num % x == 0) { Console.WriteLine(x); } } Console.ReadLine(); } } }
