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 112,415,605, 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 | 112,415,605 | |
| -1 | -112,415,605 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 112,415,605.
Example:
1 x 112,415,605 = 112,415,605
and
-1 x -112,415,605 = 112,415,605
Notice both answers equal 112,415,605
With that explanation out of the way, let's continue. Next, we take the number 112,415,605 and divide it by 2:
112,415,605 ÷ 2 = 56,207,802.5
If the quotient is a whole number, then 2 and 56,207,802.5 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 | 112,415,605 | |
| -1 | -112,415,605 |
Now, we try dividing 112,415,605 by 3:
112,415,605 ÷ 3 = 37,471,868.3333
If the quotient is a whole number, then 3 and 37,471,868.3333 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 | 112,415,605 | |
| -1 | -112,415,605 |
Let's try dividing by 4:
112,415,605 ÷ 4 = 28,103,901.25
If the quotient is a whole number, then 4 and 28,103,901.25 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 | 112,415,605 | |
| -1 | 112,415,605 |
If you did it right, you will end up with this table:
| 1 | 5 | 23 | 115 | 419 | 2,095 | 2,333 | 9,637 | 11,665 | 48,185 | 53,659 | 268,295 | 977,527 | 4,887,635 | 22,483,121 | 112,415,605 |
| -1 | -5 | -23 | -115 | -419 | -2,095 | -2,333 | -9,637 | -11,665 | -48,185 | -53,659 | -268,295 | -977,527 | -4,887,635 | -22,483,121 | -112,415,605 |
