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 35,115,355, 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 | 35,115,355 | |
| -1 | -35,115,355 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 35,115,355.
Example:
1 x 35,115,355 = 35,115,355
and
-1 x -35,115,355 = 35,115,355
Notice both answers equal 35,115,355
With that explanation out of the way, let's continue. Next, we take the number 35,115,355 and divide it by 2:
35,115,355 ÷ 2 = 17,557,677.5
If the quotient is a whole number, then 2 and 17,557,677.5 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 | 35,115,355 | |
| -1 | -35,115,355 |
Now, we try dividing 35,115,355 by 3:
35,115,355 ÷ 3 = 11,705,118.3333
If the quotient is a whole number, then 3 and 11,705,118.3333 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 | 35,115,355 | |
| -1 | -35,115,355 |
Let's try dividing by 4:
35,115,355 ÷ 4 = 8,778,838.75
If the quotient is a whole number, then 4 and 8,778,838.75 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 | 35,115,355 | |
| -1 | 35,115,355 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 55 | 383 | 1,667 | 1,915 | 4,213 | 8,335 | 18,337 | 21,065 | 91,685 | 638,461 | 3,192,305 | 7,023,071 | 35,115,355 |
| -1 | -5 | -11 | -55 | -383 | -1,667 | -1,915 | -4,213 | -8,335 | -18,337 | -21,065 | -91,685 | -638,461 | -3,192,305 | -7,023,071 | -35,115,355 |
