What numbers are factors?

A factor is a number that is multiplied. Any number can be a factor. If a number is a product of factors , each of the factors is called a divisor or a factor of that number.

Example:

180 = 3 * 10 * 6 , so 3 , 10 and 6 are factors or divisors of 180.

Also 180 = 2 * 5* 18 , so 2,5, and 18 are also factors of 180.
