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 324,474,305, 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 | 324,474,305 | |
| -1 | -324,474,305 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 324,474,305.
Example:
1 x 324,474,305 = 324,474,305
and
-1 x -324,474,305 = 324,474,305
Notice both answers equal 324,474,305
With that explanation out of the way, let's continue. Next, we take the number 324,474,305 and divide it by 2:
324,474,305 ÷ 2 = 162,237,152.5
If the quotient is a whole number, then 2 and 162,237,152.5 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 | 324,474,305 | |
| -1 | -324,474,305 |
Now, we try dividing 324,474,305 by 3:
324,474,305 ÷ 3 = 108,158,101.6667
If the quotient is a whole number, then 3 and 108,158,101.6667 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 | 324,474,305 | |
| -1 | -324,474,305 |
Let's try dividing by 4:
324,474,305 ÷ 4 = 81,118,576.25
If the quotient is a whole number, then 4 and 81,118,576.25 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 | 324,474,305 | |
| -1 | 324,474,305 |
If you did it right, you will end up with this table:
| 1 | 5 | 19 | 95 | 1,459 | 2,341 | 7,295 | 11,705 | 27,721 | 44,479 | 138,605 | 222,395 | 3,415,519 | 17,077,595 | 64,894,861 | 324,474,305 |
| -1 | -5 | -19 | -95 | -1,459 | -2,341 | -7,295 | -11,705 | -27,721 | -44,479 | -138,605 | -222,395 | -3,415,519 | -17,077,595 | -64,894,861 | -324,474,305 |
