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 236,181,101, 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 | 236,181,101 | |
| -1 | -236,181,101 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 236,181,101.
Example:
1 x 236,181,101 = 236,181,101
and
-1 x -236,181,101 = 236,181,101
Notice both answers equal 236,181,101
With that explanation out of the way, let's continue. Next, we take the number 236,181,101 and divide it by 2:
236,181,101 ÷ 2 = 118,090,550.5
If the quotient is a whole number, then 2 and 118,090,550.5 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 | 236,181,101 | |
| -1 | -236,181,101 |
Now, we try dividing 236,181,101 by 3:
236,181,101 ÷ 3 = 78,727,033.6667
If the quotient is a whole number, then 3 and 78,727,033.6667 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 | 236,181,101 | |
| -1 | -236,181,101 |
Let's try dividing by 4:
236,181,101 ÷ 4 = 59,045,275.25
If the quotient is a whole number, then 4 and 59,045,275.25 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 | 236,181,101 | |
| -1 | 236,181,101 |
If you did it right, you will end up with this table:
| 1 | 13 | 37 | 263 | 481 | 1,867 | 3,419 | 9,731 | 24,271 | 69,079 | 126,503 | 491,021 | 898,027 | 6,383,273 | 18,167,777 | 236,181,101 |
| -1 | -13 | -37 | -263 | -481 | -1,867 | -3,419 | -9,731 | -24,271 | -69,079 | -126,503 | -491,021 | -898,027 | -6,383,273 | -18,167,777 | -236,181,101 |
