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 401,332,255, 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 | 401,332,255 | |
| -1 | -401,332,255 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 401,332,255.
Example:
1 x 401,332,255 = 401,332,255
and
-1 x -401,332,255 = 401,332,255
Notice both answers equal 401,332,255
With that explanation out of the way, let's continue. Next, we take the number 401,332,255 and divide it by 2:
401,332,255 ÷ 2 = 200,666,127.5
If the quotient is a whole number, then 2 and 200,666,127.5 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 | 401,332,255 | |
| -1 | -401,332,255 |
Now, we try dividing 401,332,255 by 3:
401,332,255 ÷ 3 = 133,777,418.3333
If the quotient is a whole number, then 3 and 133,777,418.3333 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 | 401,332,255 | |
| -1 | -401,332,255 |
Let's try dividing by 4:
401,332,255 ÷ 4 = 100,333,063.75
If the quotient is a whole number, then 4 and 100,333,063.75 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 | 401,332,255 | |
| -1 | 401,332,255 |
If you did it right, you will end up with this table:
| 1 | 5 | 131 | 199 | 655 | 995 | 3,079 | 15,395 | 26,069 | 130,345 | 403,349 | 612,721 | 2,016,745 | 3,063,605 | 80,266,451 | 401,332,255 |
| -1 | -5 | -131 | -199 | -655 | -995 | -3,079 | -15,395 | -26,069 | -130,345 | -403,349 | -612,721 | -2,016,745 | -3,063,605 | -80,266,451 | -401,332,255 |
