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 442,200,115, 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 | 442,200,115 | |
| -1 | -442,200,115 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 442,200,115.
Example:
1 x 442,200,115 = 442,200,115
and
-1 x -442,200,115 = 442,200,115
Notice both answers equal 442,200,115
With that explanation out of the way, let's continue. Next, we take the number 442,200,115 and divide it by 2:
442,200,115 ÷ 2 = 221,100,057.5
If the quotient is a whole number, then 2 and 221,100,057.5 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 | 442,200,115 | |
| -1 | -442,200,115 |
Now, we try dividing 442,200,115 by 3:
442,200,115 ÷ 3 = 147,400,038.3333
If the quotient is a whole number, then 3 and 147,400,038.3333 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 | 442,200,115 | |
| -1 | -442,200,115 |
Let's try dividing by 4:
442,200,115 ÷ 4 = 110,550,028.75
If the quotient is a whole number, then 4 and 110,550,028.75 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 | 442,200,115 | |
| -1 | 442,200,115 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 103 | 515 | 721 | 3,605 | 122,663 | 613,315 | 858,641 | 4,293,205 | 12,634,289 | 63,171,445 | 88,440,023 | 442,200,115 |
| -1 | -5 | -7 | -35 | -103 | -515 | -721 | -3,605 | -122,663 | -613,315 | -858,641 | -4,293,205 | -12,634,289 | -63,171,445 | -88,440,023 | -442,200,115 |
