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 324,411,545, 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 | 324,411,545 | |
| -1 | -324,411,545 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 324,411,545.
Example:
1 x 324,411,545 = 324,411,545
and
-1 x -324,411,545 = 324,411,545
Notice both answers equal 324,411,545
With that explanation out of the way, let's continue. Next, we take the number 324,411,545 and divide it by 2:
324,411,545 ÷ 2 = 162,205,772.5
If the quotient is a whole number, then 2 and 162,205,772.5 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 | 324,411,545 | |
| -1 | -324,411,545 |
Now, we try dividing 324,411,545 by 3:
324,411,545 ÷ 3 = 108,137,181.6667
If the quotient is a whole number, then 3 and 108,137,181.6667 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 | 324,411,545 | |
| -1 | -324,411,545 |
Let's try dividing by 4:
324,411,545 ÷ 4 = 81,102,886.25
If the quotient is a whole number, then 4 and 81,102,886.25 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 | 324,411,545 | |
| -1 | 324,411,545 |
If you did it right, you will end up with this table:
| 1 | 5 | 29 | 145 | 179 | 431 | 841 | 895 | 2,155 | 4,205 | 5,191 | 12,499 | 25,955 | 62,495 | 77,149 | 150,539 | 362,471 | 385,745 | 752,695 | 1,812,355 | 2,237,321 | 11,186,605 | 64,882,309 | 324,411,545 |
| -1 | -5 | -29 | -145 | -179 | -431 | -841 | -895 | -2,155 | -4,205 | -5,191 | -12,499 | -25,955 | -62,495 | -77,149 | -150,539 | -362,471 | -385,745 | -752,695 | -1,812,355 | -2,237,321 | -11,186,605 | -64,882,309 | -324,411,545 |
