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 232,253,515, 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 | 232,253,515 | |
| -1 | -232,253,515 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 232,253,515.
Example:
1 x 232,253,515 = 232,253,515
and
-1 x -232,253,515 = 232,253,515
Notice both answers equal 232,253,515
With that explanation out of the way, let's continue. Next, we take the number 232,253,515 and divide it by 2:
232,253,515 ÷ 2 = 116,126,757.5
If the quotient is a whole number, then 2 and 116,126,757.5 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 | 232,253,515 | |
| -1 | -232,253,515 |
Now, we try dividing 232,253,515 by 3:
232,253,515 ÷ 3 = 77,417,838.3333
If the quotient is a whole number, then 3 and 77,417,838.3333 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 | 232,253,515 | |
| -1 | -232,253,515 |
Let's try dividing by 4:
232,253,515 ÷ 4 = 58,063,378.75
If the quotient is a whole number, then 4 and 58,063,378.75 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 | 232,253,515 | |
| -1 | 232,253,515 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 65 | 73 | 365 | 949 | 4,745 | 48,947 | 244,735 | 636,311 | 3,181,555 | 3,573,131 | 17,865,655 | 46,450,703 | 232,253,515 |
| -1 | -5 | -13 | -65 | -73 | -365 | -949 | -4,745 | -48,947 | -244,735 | -636,311 | -3,181,555 | -3,573,131 | -17,865,655 | -46,450,703 | -232,253,515 |
