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 115,060,555, 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 | 115,060,555 | |
| -1 | -115,060,555 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 115,060,555.
Example:
1 x 115,060,555 = 115,060,555
and
-1 x -115,060,555 = 115,060,555
Notice both answers equal 115,060,555
With that explanation out of the way, let's continue. Next, we take the number 115,060,555 and divide it by 2:
115,060,555 ÷ 2 = 57,530,277.5
If the quotient is a whole number, then 2 and 57,530,277.5 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 | 115,060,555 | |
| -1 | -115,060,555 |
Now, we try dividing 115,060,555 by 3:
115,060,555 ÷ 3 = 38,353,518.3333
If the quotient is a whole number, then 3 and 38,353,518.3333 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 | 115,060,555 | |
| -1 | -115,060,555 |
Let's try dividing by 4:
115,060,555 ÷ 4 = 28,765,138.75
If the quotient is a whole number, then 4 and 28,765,138.75 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 | 115,060,555 | |
| -1 | 115,060,555 |
If you did it right, you will end up with this table:
| 1 | 5 | 41 | 113 | 205 | 565 | 4,633 | 4,967 | 23,165 | 24,835 | 203,647 | 561,271 | 1,018,235 | 2,806,355 | 23,012,111 | 115,060,555 |
| -1 | -5 | -41 | -113 | -205 | -565 | -4,633 | -4,967 | -23,165 | -24,835 | -203,647 | -561,271 | -1,018,235 | -2,806,355 | -23,012,111 | -115,060,555 |
