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 27,833,765, 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 | 27,833,765 | |
| -1 | -27,833,765 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 27,833,765.
Example:
1 x 27,833,765 = 27,833,765
and
-1 x -27,833,765 = 27,833,765
Notice both answers equal 27,833,765
With that explanation out of the way, let's continue. Next, we take the number 27,833,765 and divide it by 2:
27,833,765 ÷ 2 = 13,916,882.5
If the quotient is a whole number, then 2 and 13,916,882.5 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 | 27,833,765 | |
| -1 | -27,833,765 |
Now, we try dividing 27,833,765 by 3:
27,833,765 ÷ 3 = 9,277,921.6667
If the quotient is a whole number, then 3 and 9,277,921.6667 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 | 27,833,765 | |
| -1 | -27,833,765 |
Let's try dividing by 4:
27,833,765 ÷ 4 = 6,958,441.25
If the quotient is a whole number, then 4 and 6,958,441.25 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 | 27,833,765 | |
| -1 | 27,833,765 |
If you did it right, you will end up with this table:
| 1 | 5 | 19 | 29 | 95 | 145 | 551 | 2,755 | 10,103 | 50,515 | 191,957 | 292,987 | 959,785 | 1,464,935 | 5,566,753 | 27,833,765 |
| -1 | -5 | -19 | -29 | -95 | -145 | -551 | -2,755 | -10,103 | -50,515 | -191,957 | -292,987 | -959,785 | -1,464,935 | -5,566,753 | -27,833,765 |
