factors

How many factors dose 30 have....

my special number 30 has alot of facors like 1 and 30 there are so many more for example.....
 * 1 and 30
 * 2 and 15
 * 3 and 10
 * 5 and 10

there are some that numbers that are not factors of 30 like 7,8,9,11,12,13,14 and more but it's going to take me to long.
