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 233,625,125, 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 | 233,625,125 | |
| -1 | -233,625,125 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 233,625,125.
Example:
1 x 233,625,125 = 233,625,125
and
-1 x -233,625,125 = 233,625,125
Notice both answers equal 233,625,125
With that explanation out of the way, let's continue. Next, we take the number 233,625,125 and divide it by 2:
233,625,125 ÷ 2 = 116,812,562.5
If the quotient is a whole number, then 2 and 116,812,562.5 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 | 233,625,125 | |
| -1 | -233,625,125 |
Now, we try dividing 233,625,125 by 3:
233,625,125 ÷ 3 = 77,875,041.6667
If the quotient is a whole number, then 3 and 77,875,041.6667 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 | 233,625,125 | |
| -1 | -233,625,125 |
Let's try dividing by 4:
233,625,125 ÷ 4 = 58,406,281.25
If the quotient is a whole number, then 4 and 58,406,281.25 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 | 233,625,125 | |
| -1 | 233,625,125 |
If you did it right, you will end up with this table:
| 1 | 5 | 25 | 125 | 977 | 1,913 | 4,885 | 9,565 | 24,425 | 47,825 | 122,125 | 239,125 | 1,869,001 | 9,345,005 | 46,725,025 | 233,625,125 |
| -1 | -5 | -25 | -125 | -977 | -1,913 | -4,885 | -9,565 | -24,425 | -47,825 | -122,125 | -239,125 | -1,869,001 | -9,345,005 | -46,725,025 | -233,625,125 |
