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 83,258,513, 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 | 83,258,513 | |
| -1 | -83,258,513 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 83,258,513.
Example:
1 x 83,258,513 = 83,258,513
and
-1 x -83,258,513 = 83,258,513
Notice both answers equal 83,258,513
With that explanation out of the way, let's continue. Next, we take the number 83,258,513 and divide it by 2:
83,258,513 ÷ 2 = 41,629,256.5
If the quotient is a whole number, then 2 and 41,629,256.5 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 | 83,258,513 | |
| -1 | -83,258,513 |
Now, we try dividing 83,258,513 by 3:
83,258,513 ÷ 3 = 27,752,837.6667
If the quotient is a whole number, then 3 and 27,752,837.6667 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 | 83,258,513 | |
| -1 | -83,258,513 |
Let's try dividing by 4:
83,258,513 ÷ 4 = 20,814,628.25
If the quotient is a whole number, then 4 and 20,814,628.25 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 | 83,258,513 | |
| -1 | 83,258,513 |
If you did it right, you will end up with this table:
| 1 | 13 | 19 | 113 | 157 | 247 | 361 | 1,469 | 2,041 | 2,147 | 2,983 | 4,693 | 17,741 | 27,911 | 38,779 | 40,793 | 56,677 | 230,633 | 337,079 | 530,309 | 736,801 | 4,382,027 | 6,404,501 | 83,258,513 |
| -1 | -13 | -19 | -113 | -157 | -247 | -361 | -1,469 | -2,041 | -2,147 | -2,983 | -4,693 | -17,741 | -27,911 | -38,779 | -40,793 | -56,677 | -230,633 | -337,079 | -530,309 | -736,801 | -4,382,027 | -6,404,501 | -83,258,513 |
