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 112,631,129, 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 | 112,631,129 | |
| -1 | -112,631,129 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 112,631,129.
Example:
1 x 112,631,129 = 112,631,129
and
-1 x -112,631,129 = 112,631,129
Notice both answers equal 112,631,129
With that explanation out of the way, let's continue. Next, we take the number 112,631,129 and divide it by 2:
112,631,129 ÷ 2 = 56,315,564.5
If the quotient is a whole number, then 2 and 56,315,564.5 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 | 112,631,129 | |
| -1 | -112,631,129 |
Now, we try dividing 112,631,129 by 3:
112,631,129 ÷ 3 = 37,543,709.6667
If the quotient is a whole number, then 3 and 37,543,709.6667 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 | 112,631,129 | |
| -1 | -112,631,129 |
Let's try dividing by 4:
112,631,129 ÷ 4 = 28,157,782.25
If the quotient is a whole number, then 4 and 28,157,782.25 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 | 112,631,129 | |
| -1 | 112,631,129 |
If you did it right, you will end up with this table:
| 1 | 13 | 47 | 337 | 547 | 611 | 4,381 | 7,111 | 15,839 | 25,709 | 184,339 | 205,907 | 334,217 | 2,396,407 | 8,663,933 | 112,631,129 |
| -1 | -13 | -47 | -337 | -547 | -611 | -4,381 | -7,111 | -15,839 | -25,709 | -184,339 | -205,907 | -334,217 | -2,396,407 | -8,663,933 | -112,631,129 |
