Unfortunately, there's not simple formula to identifying all of the factors of a number and it can be a tedious process when trying to identify the divisors of larger numbers. To find the factor combinations of the number 13,855,625, it is easier to work with a table - it's called factoring from the outside in.
We start by creating a table and writing 1 on the left side and then the number we're trying to find the factors for on the right side in a table. Then, below that, write the numbers as a negative as well.
| 1 | 13,855,625 | |
| -1 | -13,855,625 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 13,855,625.
Example:
1 x 13,855,625 = 13,855,625
and
-1 x -13,855,625 = 13,855,625
Notice both answers equal 13,855,625
With that explanation out of the way, let's continue. Next, we take the number 13,855,625 and divide it by 2:
13,855,625 ÷ 2 = 6,927,812.5
If the quotient is a whole number, then 2 and 6,927,812.5 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.
Here is what our table should look like at this step:
| 1 | 13,855,625 | |
| -1 | -13,855,625 |
Now, we try dividing 13,855,625 by 3:
13,855,625 ÷ 3 = 4,618,541.6667
If the quotient is a whole number, then 3 and 4,618,541.6667 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.
Here is what our table should look like at this step:
| 1 | 13,855,625 | |
| -1 | -13,855,625 |
Let's try dividing by 4:
13,855,625 ÷ 4 = 3,463,906.25
If the quotient is a whole number, then 4 and 3,463,906.25 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.
Here is what our table should look like at this step:
| 1 | 13,855,625 | |
| -1 | 13,855,625 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 25 | 35 | 125 | 175 | 625 | 875 | 3,167 | 4,375 | 15,835 | 22,169 | 79,175 | 110,845 | 395,875 | 554,225 | 1,979,375 | 2,771,125 | 13,855,625 |
| -1 | -5 | -7 | -25 | -35 | -125 | -175 | -625 | -875 | -3,167 | -4,375 | -15,835 | -22,169 | -79,175 | -110,845 | -395,875 | -554,225 | -1,979,375 | -2,771,125 | -13,855,625 |
