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 13,146,055, 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 | 13,146,055 | |
| -1 | -13,146,055 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 13,146,055.
Example:
1 x 13,146,055 = 13,146,055
and
-1 x -13,146,055 = 13,146,055
Notice both answers equal 13,146,055
With that explanation out of the way, let's continue. Next, we take the number 13,146,055 and divide it by 2:
13,146,055 ÷ 2 = 6,573,027.5
If the quotient is a whole number, then 2 and 6,573,027.5 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 | 13,146,055 | |
| -1 | -13,146,055 |
Now, we try dividing 13,146,055 by 3:
13,146,055 ÷ 3 = 4,382,018.3333
If the quotient is a whole number, then 3 and 4,382,018.3333 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 | 13,146,055 | |
| -1 | -13,146,055 |
Let's try dividing by 4:
13,146,055 ÷ 4 = 3,286,513.75
If the quotient is a whole number, then 4 and 3,286,513.75 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 | 13,146,055 | |
| -1 | 13,146,055 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 65 | 263 | 769 | 1,315 | 3,419 | 3,845 | 9,997 | 17,095 | 49,985 | 202,247 | 1,011,235 | 2,629,211 | 13,146,055 |
| -1 | -5 | -13 | -65 | -263 | -769 | -1,315 | -3,419 | -3,845 | -9,997 | -17,095 | -49,985 | -202,247 | -1,011,235 | -2,629,211 | -13,146,055 |
