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 13,509,395, 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 | 13,509,395 | |
| -1 | -13,509,395 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 13,509,395.
Example:
1 x 13,509,395 = 13,509,395
and
-1 x -13,509,395 = 13,509,395
Notice both answers equal 13,509,395
With that explanation out of the way, let's continue. Next, we take the number 13,509,395 and divide it by 2:
13,509,395 ÷ 2 = 6,754,697.5
If the quotient is a whole number, then 2 and 6,754,697.5 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 | 13,509,395 | |
| -1 | -13,509,395 |
Now, we try dividing 13,509,395 by 3:
13,509,395 ÷ 3 = 4,503,131.6667
If the quotient is a whole number, then 3 and 4,503,131.6667 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 | 13,509,395 | |
| -1 | -13,509,395 |
Let's try dividing by 4:
13,509,395 ÷ 4 = 3,377,348.75
If the quotient is a whole number, then 4 and 3,377,348.75 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 | 13,509,395 | |
| -1 | 13,509,395 |
If you did it right, you will end up with this table:
| 1 | 5 | 23 | 79 | 115 | 395 | 1,487 | 1,817 | 7,435 | 9,085 | 34,201 | 117,473 | 171,005 | 587,365 | 2,701,879 | 13,509,395 |
| -1 | -5 | -23 | -79 | -115 | -395 | -1,487 | -1,817 | -7,435 | -9,085 | -34,201 | -117,473 | -171,005 | -587,365 | -2,701,879 | -13,509,395 |
