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 403,455,115, 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 | 403,455,115 | |
| -1 | -403,455,115 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 403,455,115.
Example:
1 x 403,455,115 = 403,455,115
and
-1 x -403,455,115 = 403,455,115
Notice both answers equal 403,455,115
With that explanation out of the way, let's continue. Next, we take the number 403,455,115 and divide it by 2:
403,455,115 ÷ 2 = 201,727,557.5
If the quotient is a whole number, then 2 and 201,727,557.5 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 | 403,455,115 | |
| -1 | -403,455,115 |
Now, we try dividing 403,455,115 by 3:
403,455,115 ÷ 3 = 134,485,038.3333
If the quotient is a whole number, then 3 and 134,485,038.3333 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 | 403,455,115 | |
| -1 | -403,455,115 |
Let's try dividing by 4:
403,455,115 ÷ 4 = 100,863,778.75
If the quotient is a whole number, then 4 and 100,863,778.75 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 | 403,455,115 | |
| -1 | 403,455,115 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 83 | 415 | 581 | 2,905 | 138,883 | 694,415 | 972,181 | 4,860,905 | 11,527,289 | 57,636,445 | 80,691,023 | 403,455,115 |
| -1 | -5 | -7 | -35 | -83 | -415 | -581 | -2,905 | -138,883 | -694,415 | -972,181 | -4,860,905 | -11,527,289 | -57,636,445 | -80,691,023 | -403,455,115 |
