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 36,078,115, 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 | 36,078,115 | |
| -1 | -36,078,115 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 36,078,115.
Example:
1 x 36,078,115 = 36,078,115
and
-1 x -36,078,115 = 36,078,115
Notice both answers equal 36,078,115
With that explanation out of the way, let's continue. Next, we take the number 36,078,115 and divide it by 2:
36,078,115 ÷ 2 = 18,039,057.5
If the quotient is a whole number, then 2 and 18,039,057.5 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 | 36,078,115 | |
| -1 | -36,078,115 |
Now, we try dividing 36,078,115 by 3:
36,078,115 ÷ 3 = 12,026,038.3333
If the quotient is a whole number, then 3 and 12,026,038.3333 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 | 36,078,115 | |
| -1 | -36,078,115 |
Let's try dividing by 4:
36,078,115 ÷ 4 = 9,019,528.75
If the quotient is a whole number, then 4 and 9,019,528.75 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 | 36,078,115 | |
| -1 | 36,078,115 |
If you did it right, you will end up with this table:
| 1 | 5 | 79 | 149 | 395 | 613 | 745 | 3,065 | 11,771 | 48,427 | 58,855 | 91,337 | 242,135 | 456,685 | 7,215,623 | 36,078,115 |
| -1 | -5 | -79 | -149 | -395 | -613 | -745 | -3,065 | -11,771 | -48,427 | -58,855 | -91,337 | -242,135 | -456,685 | -7,215,623 | -36,078,115 |
