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 13,036,265, 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 | 13,036,265 | |
| -1 | -13,036,265 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 13,036,265.
Example:
1 x 13,036,265 = 13,036,265
and
-1 x -13,036,265 = 13,036,265
Notice both answers equal 13,036,265
With that explanation out of the way, let's continue. Next, we take the number 13,036,265 and divide it by 2:
13,036,265 ÷ 2 = 6,518,132.5
If the quotient is a whole number, then 2 and 6,518,132.5 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 | 13,036,265 | |
| -1 | -13,036,265 |
Now, we try dividing 13,036,265 by 3:
13,036,265 ÷ 3 = 4,345,421.6667
If the quotient is a whole number, then 3 and 4,345,421.6667 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 | 13,036,265 | |
| -1 | -13,036,265 |
Let's try dividing by 4:
13,036,265 ÷ 4 = 3,259,066.25
If the quotient is a whole number, then 4 and 3,259,066.25 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 | 13,036,265 | |
| -1 | 13,036,265 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 55 | 421 | 563 | 2,105 | 2,815 | 4,631 | 6,193 | 23,155 | 30,965 | 237,023 | 1,185,115 | 2,607,253 | 13,036,265 |
| -1 | -5 | -11 | -55 | -421 | -563 | -2,105 | -2,815 | -4,631 | -6,193 | -23,155 | -30,965 | -237,023 | -1,185,115 | -2,607,253 | -13,036,265 |
