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 115,251,323, 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 | 115,251,323 | |
| -1 | -115,251,323 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 115,251,323.
Example:
1 x 115,251,323 = 115,251,323
and
-1 x -115,251,323 = 115,251,323
Notice both answers equal 115,251,323
With that explanation out of the way, let's continue. Next, we take the number 115,251,323 and divide it by 2:
115,251,323 ÷ 2 = 57,625,661.5
If the quotient is a whole number, then 2 and 57,625,661.5 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 | 115,251,323 | |
| -1 | -115,251,323 |
Now, we try dividing 115,251,323 by 3:
115,251,323 ÷ 3 = 38,417,107.6667
If the quotient is a whole number, then 3 and 38,417,107.6667 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 | 115,251,323 | |
| -1 | -115,251,323 |
Let's try dividing by 4:
115,251,323 ÷ 4 = 28,812,830.75
If the quotient is a whole number, then 4 and 28,812,830.75 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 | 115,251,323 | |
| -1 | 115,251,323 |
If you did it right, you will end up with this table:
| 1 | 11 | 67 | 353 | 443 | 737 | 3,883 | 4,873 | 23,651 | 29,681 | 156,379 | 260,161 | 326,491 | 1,720,169 | 10,477,393 | 115,251,323 |
| -1 | -11 | -67 | -353 | -443 | -737 | -3,883 | -4,873 | -23,651 | -29,681 | -156,379 | -260,161 | -326,491 | -1,720,169 | -10,477,393 | -115,251,323 |
