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 231,525,095, 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 | 231,525,095 | |
| -1 | -231,525,095 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 231,525,095.
Example:
1 x 231,525,095 = 231,525,095
and
-1 x -231,525,095 = 231,525,095
Notice both answers equal 231,525,095
With that explanation out of the way, let's continue. Next, we take the number 231,525,095 and divide it by 2:
231,525,095 ÷ 2 = 115,762,547.5
If the quotient is a whole number, then 2 and 115,762,547.5 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 | 231,525,095 | |
| -1 | -231,525,095 |
Now, we try dividing 231,525,095 by 3:
231,525,095 ÷ 3 = 77,175,031.6667
If the quotient is a whole number, then 3 and 77,175,031.6667 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 | 231,525,095 | |
| -1 | -231,525,095 |
Let's try dividing by 4:
231,525,095 ÷ 4 = 57,881,273.75
If the quotient is a whole number, then 4 and 57,881,273.75 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 | 231,525,095 | |
| -1 | 231,525,095 |
If you did it right, you will end up with this table:
| 1 | 5 | 37 | 185 | 773 | 1,619 | 3,865 | 8,095 | 28,601 | 59,903 | 143,005 | 299,515 | 1,251,487 | 6,257,435 | 46,305,019 | 231,525,095 |
| -1 | -5 | -37 | -185 | -773 | -1,619 | -3,865 | -8,095 | -28,601 | -59,903 | -143,005 | -299,515 | -1,251,487 | -6,257,435 | -46,305,019 | -231,525,095 |
