The **factors** of a number are those that are contained in the same number an exact number of times. In fact, when calculating the gcf of two numbers we are calculating the greatest common divisor of both.

Therefore, given a number, another number is its divisor as long as they are divisible by it.

for example:

How to find the factors of a number

**Divide the number whenever possible by the smallest prime number that can be divided.**For example, with the number 256 we divide it by the smallest prime number whenever possible:

256/2=128

128/2=64

64/2=32

32/2=16

16/2=8

8/2=4

4/2=2

2/2=1

So the result is: 1, 2, 4, 8, 16, 32, 64, 128 y 256.**Every natural number always has as its divisors itself and 1.**In the previous step it is verified that 256 can effectively be divided between itself and 1.
