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 236,355,223, 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 | 236,355,223 | |
| -1 | -236,355,223 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 236,355,223.
Example:
1 x 236,355,223 = 236,355,223
and
-1 x -236,355,223 = 236,355,223
Notice both answers equal 236,355,223
With that explanation out of the way, let's continue. Next, we take the number 236,355,223 and divide it by 2:
236,355,223 ÷ 2 = 118,177,611.5
If the quotient is a whole number, then 2 and 118,177,611.5 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 | 236,355,223 | |
| -1 | -236,355,223 |
Now, we try dividing 236,355,223 by 3:
236,355,223 ÷ 3 = 78,785,074.3333
If the quotient is a whole number, then 3 and 78,785,074.3333 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 | 236,355,223 | |
| -1 | -236,355,223 |
Let's try dividing by 4:
236,355,223 ÷ 4 = 59,088,805.75
If the quotient is a whole number, then 4 and 59,088,805.75 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 | 236,355,223 | |
| -1 | 236,355,223 |
If you did it right, you will end up with this table:
| 1 | 13 | 37 | 481 | 487 | 1,009 | 6,331 | 13,117 | 18,019 | 37,333 | 234,247 | 485,329 | 491,383 | 6,387,979 | 18,181,171 | 236,355,223 |
| -1 | -13 | -37 | -481 | -487 | -1,009 | -6,331 | -13,117 | -18,019 | -37,333 | -234,247 | -485,329 | -491,383 | -6,387,979 | -18,181,171 | -236,355,223 |
