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 112,115,311, 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 | 112,115,311 | |
| -1 | -112,115,311 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 112,115,311.
Example:
1 x 112,115,311 = 112,115,311
and
-1 x -112,115,311 = 112,115,311
Notice both answers equal 112,115,311
With that explanation out of the way, let's continue. Next, we take the number 112,115,311 and divide it by 2:
112,115,311 ÷ 2 = 56,057,655.5
If the quotient is a whole number, then 2 and 56,057,655.5 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 | 112,115,311 | |
| -1 | -112,115,311 |
Now, we try dividing 112,115,311 by 3:
112,115,311 ÷ 3 = 37,371,770.3333
If the quotient is a whole number, then 3 and 37,371,770.3333 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 | 112,115,311 | |
| -1 | -112,115,311 |
Let's try dividing by 4:
112,115,311 ÷ 4 = 28,028,827.75
If the quotient is a whole number, then 4 and 28,028,827.75 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 | 112,115,311 | |
| -1 | 112,115,311 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 77 | 857 | 1,699 | 5,999 | 9,427 | 11,893 | 18,689 | 65,989 | 130,823 | 1,456,043 | 10,192,301 | 16,016,473 | 112,115,311 |
| -1 | -7 | -11 | -77 | -857 | -1,699 | -5,999 | -9,427 | -11,893 | -18,689 | -65,989 | -130,823 | -1,456,043 | -10,192,301 | -16,016,473 | -112,115,311 |
