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 115,743,055, 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 | 115,743,055 | |
| -1 | -115,743,055 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 115,743,055.
Example:
1 x 115,743,055 = 115,743,055
and
-1 x -115,743,055 = 115,743,055
Notice both answers equal 115,743,055
With that explanation out of the way, let's continue. Next, we take the number 115,743,055 and divide it by 2:
115,743,055 ÷ 2 = 57,871,527.5
If the quotient is a whole number, then 2 and 57,871,527.5 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 | 115,743,055 | |
| -1 | -115,743,055 |
Now, we try dividing 115,743,055 by 3:
115,743,055 ÷ 3 = 38,581,018.3333
If the quotient is a whole number, then 3 and 38,581,018.3333 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 | 115,743,055 | |
| -1 | -115,743,055 |
Let's try dividing by 4:
115,743,055 ÷ 4 = 28,935,763.75
If the quotient is a whole number, then 4 and 28,935,763.75 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 | 115,743,055 | |
| -1 | 115,743,055 |
If you did it right, you will end up with this table:
| 1 | 5 | 17 | 85 | 173 | 289 | 463 | 865 | 1,445 | 2,315 | 2,941 | 7,871 | 14,705 | 39,355 | 49,997 | 80,099 | 133,807 | 249,985 | 400,495 | 669,035 | 1,361,683 | 6,808,415 | 23,148,611 | 115,743,055 |
| -1 | -5 | -17 | -85 | -173 | -289 | -463 | -865 | -1,445 | -2,315 | -2,941 | -7,871 | -14,705 | -39,355 | -49,997 | -80,099 | -133,807 | -249,985 | -400,495 | -669,035 | -1,361,683 | -6,808,415 | -23,148,611 | -115,743,055 |
