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 324,484,825, 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 | 324,484,825 | |
| -1 | -324,484,825 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 324,484,825.
Example:
1 x 324,484,825 = 324,484,825
and
-1 x -324,484,825 = 324,484,825
Notice both answers equal 324,484,825
With that explanation out of the way, let's continue. Next, we take the number 324,484,825 and divide it by 2:
324,484,825 ÷ 2 = 162,242,412.5
If the quotient is a whole number, then 2 and 162,242,412.5 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 | 324,484,825 | |
| -1 | -324,484,825 |
Now, we try dividing 324,484,825 by 3:
324,484,825 ÷ 3 = 108,161,608.3333
If the quotient is a whole number, then 3 and 108,161,608.3333 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 | 324,484,825 | |
| -1 | -324,484,825 |
Let's try dividing by 4:
324,484,825 ÷ 4 = 81,121,206.25
If the quotient is a whole number, then 4 and 81,121,206.25 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 | 324,484,825 | |
| -1 | 324,484,825 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 25 | 35 | 109 | 175 | 545 | 763 | 2,725 | 3,815 | 17,011 | 19,075 | 85,055 | 119,077 | 425,275 | 595,385 | 1,854,199 | 2,976,925 | 9,270,995 | 12,979,393 | 46,354,975 | 64,896,965 | 324,484,825 |
| -1 | -5 | -7 | -25 | -35 | -109 | -175 | -545 | -763 | -2,725 | -3,815 | -17,011 | -19,075 | -85,055 | -119,077 | -425,275 | -595,385 | -1,854,199 | -2,976,925 | -9,270,995 | -12,979,393 | -46,354,975 | -64,896,965 | -324,484,825 |
