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 13,475,515, 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 | 13,475,515 | |
| -1 | -13,475,515 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 13,475,515.
Example:
1 x 13,475,515 = 13,475,515
and
-1 x -13,475,515 = 13,475,515
Notice both answers equal 13,475,515
With that explanation out of the way, let's continue. Next, we take the number 13,475,515 and divide it by 2:
13,475,515 ÷ 2 = 6,737,757.5
If the quotient is a whole number, then 2 and 6,737,757.5 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 | 13,475,515 | |
| -1 | -13,475,515 |
Now, we try dividing 13,475,515 by 3:
13,475,515 ÷ 3 = 4,491,838.3333
If the quotient is a whole number, then 3 and 4,491,838.3333 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 | 13,475,515 | |
| -1 | -13,475,515 |
Let's try dividing by 4:
13,475,515 ÷ 4 = 3,368,878.75
If the quotient is a whole number, then 4 and 3,368,878.75 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 | 13,475,515 | |
| -1 | 13,475,515 |
If you did it right, you will end up with this table:
| 1 | 5 | 53 | 211 | 241 | 265 | 1,055 | 1,205 | 11,183 | 12,773 | 50,851 | 55,915 | 63,865 | 254,255 | 2,695,103 | 13,475,515 |
| -1 | -5 | -53 | -211 | -241 | -265 | -1,055 | -1,205 | -11,183 | -12,773 | -50,851 | -55,915 | -63,865 | -254,255 | -2,695,103 | -13,475,515 |
