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 324,126,625, 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 | 324,126,625 | |
| -1 | -324,126,625 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 324,126,625.
Example:
1 x 324,126,625 = 324,126,625
and
-1 x -324,126,625 = 324,126,625
Notice both answers equal 324,126,625
With that explanation out of the way, let's continue. Next, we take the number 324,126,625 and divide it by 2:
324,126,625 ÷ 2 = 162,063,312.5
If the quotient is a whole number, then 2 and 162,063,312.5 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 | 324,126,625 | |
| -1 | -324,126,625 |
Now, we try dividing 324,126,625 by 3:
324,126,625 ÷ 3 = 108,042,208.3333
If the quotient is a whole number, then 3 and 108,042,208.3333 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 | 324,126,625 | |
| -1 | -324,126,625 |
Let's try dividing by 4:
324,126,625 ÷ 4 = 81,031,656.25
If the quotient is a whole number, then 4 and 81,031,656.25 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 | 324,126,625 | |
| -1 | 324,126,625 |
If you did it right, you will end up with this table:
| 1 | 5 | 25 | 125 | 541 | 2,705 | 4,793 | 13,525 | 23,965 | 67,625 | 119,825 | 599,125 | 2,593,013 | 12,965,065 | 64,825,325 | 324,126,625 |
| -1 | -5 | -25 | -125 | -541 | -2,705 | -4,793 | -13,525 | -23,965 | -67,625 | -119,825 | -599,125 | -2,593,013 | -12,965,065 | -64,825,325 | -324,126,625 |
