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 112,504,105, 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 | 112,504,105 | |
| -1 | -112,504,105 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 112,504,105.
Example:
1 x 112,504,105 = 112,504,105
and
-1 x -112,504,105 = 112,504,105
Notice both answers equal 112,504,105
With that explanation out of the way, let's continue. Next, we take the number 112,504,105 and divide it by 2:
112,504,105 ÷ 2 = 56,252,052.5
If the quotient is a whole number, then 2 and 56,252,052.5 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 | 112,504,105 | |
| -1 | -112,504,105 |
Now, we try dividing 112,504,105 by 3:
112,504,105 ÷ 3 = 37,501,368.3333
If the quotient is a whole number, then 3 and 37,501,368.3333 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 | 112,504,105 | |
| -1 | -112,504,105 |
Let's try dividing by 4:
112,504,105 ÷ 4 = 28,126,026.25
If the quotient is a whole number, then 4 and 28,126,026.25 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 | 112,504,105 | |
| -1 | 112,504,105 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 1,319 | 2,437 | 6,595 | 9,233 | 12,185 | 17,059 | 46,165 | 85,295 | 3,214,403 | 16,072,015 | 22,500,821 | 112,504,105 |
| -1 | -5 | -7 | -35 | -1,319 | -2,437 | -6,595 | -9,233 | -12,185 | -17,059 | -46,165 | -85,295 | -3,214,403 | -16,072,015 | -22,500,821 | -112,504,105 |
