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 405,200,003, 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 | 405,200,003 | |
| -1 | -405,200,003 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 405,200,003.
Example:
1 x 405,200,003 = 405,200,003
and
-1 x -405,200,003 = 405,200,003
Notice both answers equal 405,200,003
With that explanation out of the way, let's continue. Next, we take the number 405,200,003 and divide it by 2:
405,200,003 ÷ 2 = 202,600,001.5
If the quotient is a whole number, then 2 and 202,600,001.5 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 | 405,200,003 | |
| -1 | -405,200,003 |
Now, we try dividing 405,200,003 by 3:
405,200,003 ÷ 3 = 135,066,667.6667
If the quotient is a whole number, then 3 and 135,066,667.6667 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 | 405,200,003 | |
| -1 | -405,200,003 |
Let's try dividing by 4:
405,200,003 ÷ 4 = 101,300,000.75
If the quotient is a whole number, then 4 and 101,300,000.75 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 | 405,200,003 | |
| -1 | 405,200,003 |
If you did it right, you will end up with this table:
| 1 | 13 | 61 | 523 | 793 | 977 | 6,799 | 12,701 | 31,903 | 59,597 | 414,739 | 510,971 | 774,761 | 6,642,623 | 31,169,231 | 405,200,003 |
| -1 | -13 | -61 | -523 | -793 | -977 | -6,799 | -12,701 | -31,903 | -59,597 | -414,739 | -510,971 | -774,761 | -6,642,623 | -31,169,231 | -405,200,003 |
