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 324,532,997, 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 | 324,532,997 | |
| -1 | -324,532,997 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 324,532,997.
Example:
1 x 324,532,997 = 324,532,997
and
-1 x -324,532,997 = 324,532,997
Notice both answers equal 324,532,997
With that explanation out of the way, let's continue. Next, we take the number 324,532,997 and divide it by 2:
324,532,997 ÷ 2 = 162,266,498.5
If the quotient is a whole number, then 2 and 162,266,498.5 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 | 324,532,997 | |
| -1 | -324,532,997 |
Now, we try dividing 324,532,997 by 3:
324,532,997 ÷ 3 = 108,177,665.6667
If the quotient is a whole number, then 3 and 108,177,665.6667 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 | 324,532,997 | |
| -1 | -324,532,997 |
Let's try dividing by 4:
324,532,997 ÷ 4 = 81,133,249.25
If the quotient is a whole number, then 4 and 81,133,249.25 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 | 324,532,997 | |
| -1 | 324,532,997 |
If you did it right, you will end up with this table:
| 1 | 29 | 43 | 97 | 1,247 | 2,683 | 2,813 | 4,171 | 77,807 | 115,369 | 120,959 | 260,251 | 3,345,701 | 7,547,279 | 11,190,793 | 324,532,997 |
| -1 | -29 | -43 | -97 | -1,247 | -2,683 | -2,813 | -4,171 | -77,807 | -115,369 | -120,959 | -260,251 | -3,345,701 | -7,547,279 | -11,190,793 | -324,532,997 |
