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 324,242,215, 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 | 324,242,215 | |
| -1 | -324,242,215 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 324,242,215.
Example:
1 x 324,242,215 = 324,242,215
and
-1 x -324,242,215 = 324,242,215
Notice both answers equal 324,242,215
With that explanation out of the way, let's continue. Next, we take the number 324,242,215 and divide it by 2:
324,242,215 ÷ 2 = 162,121,107.5
If the quotient is a whole number, then 2 and 162,121,107.5 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 | 324,242,215 | |
| -1 | -324,242,215 |
Now, we try dividing 324,242,215 by 3:
324,242,215 ÷ 3 = 108,080,738.3333
If the quotient is a whole number, then 3 and 108,080,738.3333 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 | 324,242,215 | |
| -1 | -324,242,215 |
Let's try dividing by 4:
324,242,215 ÷ 4 = 81,060,553.75
If the quotient is a whole number, then 4 and 81,060,553.75 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 | 324,242,215 | |
| -1 | 324,242,215 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 55 | 1,787 | 3,299 | 8,935 | 16,495 | 19,657 | 36,289 | 98,285 | 181,445 | 5,895,313 | 29,476,565 | 64,848,443 | 324,242,215 |
| -1 | -5 | -11 | -55 | -1,787 | -3,299 | -8,935 | -16,495 | -19,657 | -36,289 | -98,285 | -181,445 | -5,895,313 | -29,476,565 | -64,848,443 | -324,242,215 |
