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 13,010,023, 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 | 13,010,023 | |
| -1 | -13,010,023 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 13,010,023.
Example:
1 x 13,010,023 = 13,010,023
and
-1 x -13,010,023 = 13,010,023
Notice both answers equal 13,010,023
With that explanation out of the way, let's continue. Next, we take the number 13,010,023 and divide it by 2:
13,010,023 ÷ 2 = 6,505,011.5
If the quotient is a whole number, then 2 and 6,505,011.5 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 | 13,010,023 | |
| -1 | -13,010,023 |
Now, we try dividing 13,010,023 by 3:
13,010,023 ÷ 3 = 4,336,674.3333
If the quotient is a whole number, then 3 and 4,336,674.3333 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 | 13,010,023 | |
| -1 | -13,010,023 |
Let's try dividing by 4:
13,010,023 ÷ 4 = 3,252,505.75
If the quotient is a whole number, then 4 and 3,252,505.75 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 | 13,010,023 | |
| -1 | 13,010,023 |
If you did it right, you will end up with this table:
| 1 | 13 | 47 | 107 | 199 | 611 | 1,391 | 2,587 | 5,029 | 9,353 | 21,293 | 65,377 | 121,589 | 276,809 | 1,000,771 | 13,010,023 |
| -1 | -13 | -47 | -107 | -199 | -611 | -1,391 | -2,587 | -5,029 | -9,353 | -21,293 | -65,377 | -121,589 | -276,809 | -1,000,771 | -13,010,023 |
