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 27,083,371, 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 | 27,083,371 | |
| -1 | -27,083,371 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 27,083,371.
Example:
1 x 27,083,371 = 27,083,371
and
-1 x -27,083,371 = 27,083,371
Notice both answers equal 27,083,371
With that explanation out of the way, let's continue. Next, we take the number 27,083,371 and divide it by 2:
27,083,371 ÷ 2 = 13,541,685.5
If the quotient is a whole number, then 2 and 13,541,685.5 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 | 27,083,371 | |
| -1 | -27,083,371 |
Now, we try dividing 27,083,371 by 3:
27,083,371 ÷ 3 = 9,027,790.3333
If the quotient is a whole number, then 3 and 9,027,790.3333 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 | 27,083,371 | |
| -1 | -27,083,371 |
Let's try dividing by 4:
27,083,371 ÷ 4 = 6,770,842.75
If the quotient is a whole number, then 4 and 6,770,842.75 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 | 27,083,371 | |
| -1 | 27,083,371 |
If you did it right, you will end up with this table:
| 1 | 7 | 37 | 53 | 259 | 371 | 1,961 | 1,973 | 13,727 | 13,811 | 73,001 | 104,569 | 511,007 | 731,983 | 3,869,053 | 27,083,371 |
| -1 | -7 | -37 | -53 | -259 | -371 | -1,961 | -1,973 | -13,727 | -13,811 | -73,001 | -104,569 | -511,007 | -731,983 | -3,869,053 | -27,083,371 |
