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 404,512,145, 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 | 404,512,145 | |
| -1 | -404,512,145 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 404,512,145.
Example:
1 x 404,512,145 = 404,512,145
and
-1 x -404,512,145 = 404,512,145
Notice both answers equal 404,512,145
With that explanation out of the way, let's continue. Next, we take the number 404,512,145 and divide it by 2:
404,512,145 ÷ 2 = 202,256,072.5
If the quotient is a whole number, then 2 and 202,256,072.5 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 | 404,512,145 | |
| -1 | -404,512,145 |
Now, we try dividing 404,512,145 by 3:
404,512,145 ÷ 3 = 134,837,381.6667
If the quotient is a whole number, then 3 and 134,837,381.6667 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 | 404,512,145 | |
| -1 | -404,512,145 |
Let's try dividing by 4:
404,512,145 ÷ 4 = 101,128,036.25
If the quotient is a whole number, then 4 and 101,128,036.25 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 | 404,512,145 | |
| -1 | 404,512,145 |
If you did it right, you will end up with this table:
| 1 | 5 | 127 | 281 | 635 | 1,405 | 2,267 | 11,335 | 35,687 | 178,435 | 287,909 | 637,027 | 1,439,545 | 3,185,135 | 80,902,429 | 404,512,145 |
| -1 | -5 | -127 | -281 | -635 | -1,405 | -2,267 | -11,335 | -35,687 | -178,435 | -287,909 | -637,027 | -1,439,545 | -3,185,135 | -80,902,429 | -404,512,145 |
