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 13,301,155, 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 | 13,301,155 | |
| -1 | -13,301,155 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 13,301,155.
Example:
1 x 13,301,155 = 13,301,155
and
-1 x -13,301,155 = 13,301,155
Notice both answers equal 13,301,155
With that explanation out of the way, let's continue. Next, we take the number 13,301,155 and divide it by 2:
13,301,155 ÷ 2 = 6,650,577.5
If the quotient is a whole number, then 2 and 6,650,577.5 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 | 13,301,155 | |
| -1 | -13,301,155 |
Now, we try dividing 13,301,155 by 3:
13,301,155 ÷ 3 = 4,433,718.3333
If the quotient is a whole number, then 3 and 4,433,718.3333 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 | 13,301,155 | |
| -1 | -13,301,155 |
Let's try dividing by 4:
13,301,155 ÷ 4 = 3,325,288.75
If the quotient is a whole number, then 4 and 3,325,288.75 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 | 13,301,155 | |
| -1 | 13,301,155 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 419 | 907 | 2,095 | 2,933 | 4,535 | 6,349 | 14,665 | 31,745 | 380,033 | 1,900,165 | 2,660,231 | 13,301,155 |
| -1 | -5 | -7 | -35 | -419 | -907 | -2,095 | -2,933 | -4,535 | -6,349 | -14,665 | -31,745 | -380,033 | -1,900,165 | -2,660,231 | -13,301,155 |
