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 405,463,045, 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 | 405,463,045 | |
| -1 | -405,463,045 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 405,463,045.
Example:
1 x 405,463,045 = 405,463,045
and
-1 x -405,463,045 = 405,463,045
Notice both answers equal 405,463,045
With that explanation out of the way, let's continue. Next, we take the number 405,463,045 and divide it by 2:
405,463,045 ÷ 2 = 202,731,522.5
If the quotient is a whole number, then 2 and 202,731,522.5 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 | 405,463,045 | |
| -1 | -405,463,045 |
Now, we try dividing 405,463,045 by 3:
405,463,045 ÷ 3 = 135,154,348.3333
If the quotient is a whole number, then 3 and 135,154,348.3333 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 | 405,463,045 | |
| -1 | -405,463,045 |
Let's try dividing by 4:
405,463,045 ÷ 4 = 101,365,761.25
If the quotient is a whole number, then 4 and 101,365,761.25 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 | 405,463,045 | |
| -1 | 405,463,045 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 59 | 65 | 295 | 767 | 3,835 | 105,727 | 528,635 | 1,374,451 | 6,237,893 | 6,872,255 | 31,189,465 | 81,092,609 | 405,463,045 |
| -1 | -5 | -13 | -59 | -65 | -295 | -767 | -3,835 | -105,727 | -528,635 | -1,374,451 | -6,237,893 | -6,872,255 | -31,189,465 | -81,092,609 | -405,463,045 |
