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 112,572,755, 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 | 112,572,755 | |
| -1 | -112,572,755 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 112,572,755.
Example:
1 x 112,572,755 = 112,572,755
and
-1 x -112,572,755 = 112,572,755
Notice both answers equal 112,572,755
With that explanation out of the way, let's continue. Next, we take the number 112,572,755 and divide it by 2:
112,572,755 ÷ 2 = 56,286,377.5
If the quotient is a whole number, then 2 and 56,286,377.5 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 | 112,572,755 | |
| -1 | -112,572,755 |
Now, we try dividing 112,572,755 by 3:
112,572,755 ÷ 3 = 37,524,251.6667
If the quotient is a whole number, then 3 and 37,524,251.6667 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 | 112,572,755 | |
| -1 | -112,572,755 |
Let's try dividing by 4:
112,572,755 ÷ 4 = 28,143,188.75
If the quotient is a whole number, then 4 and 28,143,188.75 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 | 112,572,755 | |
| -1 | 112,572,755 |
If you did it right, you will end up with this table:
| 1 | 5 | 47 | 61 | 235 | 305 | 2,867 | 7,853 | 14,335 | 39,265 | 369,091 | 479,033 | 1,845,455 | 2,395,165 | 22,514,551 | 112,572,755 |
| -1 | -5 | -47 | -61 | -235 | -305 | -2,867 | -7,853 | -14,335 | -39,265 | -369,091 | -479,033 | -1,845,455 | -2,395,165 | -22,514,551 | -112,572,755 |
