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 324,504,103, 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 | 324,504,103 | |
| -1 | -324,504,103 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 324,504,103.
Example:
1 x 324,504,103 = 324,504,103
and
-1 x -324,504,103 = 324,504,103
Notice both answers equal 324,504,103
With that explanation out of the way, let's continue. Next, we take the number 324,504,103 and divide it by 2:
324,504,103 ÷ 2 = 162,252,051.5
If the quotient is a whole number, then 2 and 162,252,051.5 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 | 324,504,103 | |
| -1 | -324,504,103 |
Now, we try dividing 324,504,103 by 3:
324,504,103 ÷ 3 = 108,168,034.3333
If the quotient is a whole number, then 3 and 108,168,034.3333 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 | 324,504,103 | |
| -1 | -324,504,103 |
Let's try dividing by 4:
324,504,103 ÷ 4 = 81,126,025.75
If the quotient is a whole number, then 4 and 81,126,025.75 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 | 324,504,103 | |
| -1 | 324,504,103 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 77 | 1,913 | 2,203 | 13,391 | 15,421 | 21,043 | 24,233 | 147,301 | 169,631 | 4,214,339 | 29,500,373 | 46,357,729 | 324,504,103 |
| -1 | -7 | -11 | -77 | -1,913 | -2,203 | -13,391 | -15,421 | -21,043 | -24,233 | -147,301 | -169,631 | -4,214,339 | -29,500,373 | -46,357,729 | -324,504,103 |
