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 115,671,347, 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 | 115,671,347 | |
| -1 | -115,671,347 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 115,671,347.
Example:
1 x 115,671,347 = 115,671,347
and
-1 x -115,671,347 = 115,671,347
Notice both answers equal 115,671,347
With that explanation out of the way, let's continue. Next, we take the number 115,671,347 and divide it by 2:
115,671,347 ÷ 2 = 57,835,673.5
If the quotient is a whole number, then 2 and 57,835,673.5 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 | 115,671,347 | |
| -1 | -115,671,347 |
Now, we try dividing 115,671,347 by 3:
115,671,347 ÷ 3 = 38,557,115.6667
If the quotient is a whole number, then 3 and 38,557,115.6667 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 | 115,671,347 | |
| -1 | -115,671,347 |
Let's try dividing by 4:
115,671,347 ÷ 4 = 28,917,836.75
If the quotient is a whole number, then 4 and 28,917,836.75 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 | 115,671,347 | |
| -1 | 115,671,347 |
If you did it right, you will end up with this table:
| 1 | 11 | 23 | 73 | 253 | 803 | 1,679 | 6,263 | 18,469 | 68,893 | 144,049 | 457,199 | 1,584,539 | 5,029,189 | 10,515,577 | 115,671,347 |
| -1 | -11 | -23 | -73 | -253 | -803 | -1,679 | -6,263 | -18,469 | -68,893 | -144,049 | -457,199 | -1,584,539 | -5,029,189 | -10,515,577 | -115,671,347 |
