The prime factors of 221 are 13 and 17. They're the only prime numbers that will divide evenly into 221 with no remainder.
Because the only whole numbers that divide into 17, without remainder, are 1 and 17 itself.
Since 5 is a prime number only the numbers 1 and 5 divide it without a remainder.
To find a prime factor of a number, divide by 2 and see if you get no remainder. Then divide by 3, 4, 5, and so on, until one of the numbers you try gets you no remainder. If no such numbers work below the number you chose, it is prime. In the case of the number 9, 2 does not go into 9, but 3 does.
