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 113,136,023, 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 | 113,136,023 | |
| -1 | -113,136,023 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 113,136,023.
Example:
1 x 113,136,023 = 113,136,023
and
-1 x -113,136,023 = 113,136,023
Notice both answers equal 113,136,023
With that explanation out of the way, let's continue. Next, we take the number 113,136,023 and divide it by 2:
113,136,023 ÷ 2 = 56,568,011.5
If the quotient is a whole number, then 2 and 56,568,011.5 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 | 113,136,023 | |
| -1 | -113,136,023 |
Now, we try dividing 113,136,023 by 3:
113,136,023 ÷ 3 = 37,712,007.6667
If the quotient is a whole number, then 3 and 37,712,007.6667 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 | 113,136,023 | |
| -1 | -113,136,023 |
Let's try dividing by 4:
113,136,023 ÷ 4 = 28,284,005.75
If the quotient is a whole number, then 4 and 28,284,005.75 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 | 113,136,023 | |
| -1 | 113,136,023 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 13 | 77 | 91 | 143 | 1,001 | 113,023 | 791,161 | 1,243,253 | 1,469,299 | 8,702,771 | 10,285,093 | 16,162,289 | 113,136,023 |
| -1 | -7 | -11 | -13 | -77 | -91 | -143 | -1,001 | -113,023 | -791,161 | -1,243,253 | -1,469,299 | -8,702,771 | -10,285,093 | -16,162,289 | -113,136,023 |
