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 27,867,743, 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 | 27,867,743 | |
| -1 | -27,867,743 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 27,867,743.
Example:
1 x 27,867,743 = 27,867,743
and
-1 x -27,867,743 = 27,867,743
Notice both answers equal 27,867,743
With that explanation out of the way, let's continue. Next, we take the number 27,867,743 and divide it by 2:
27,867,743 ÷ 2 = 13,933,871.5
If the quotient is a whole number, then 2 and 13,933,871.5 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 | 27,867,743 | |
| -1 | -27,867,743 |
Now, we try dividing 27,867,743 by 3:
27,867,743 ÷ 3 = 9,289,247.6667
If the quotient is a whole number, then 3 and 9,289,247.6667 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 | 27,867,743 | |
| -1 | -27,867,743 |
Let's try dividing by 4:
27,867,743 ÷ 4 = 6,966,935.75
If the quotient is a whole number, then 4 and 6,966,935.75 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 | 27,867,743 | |
| -1 | 27,867,743 |
If you did it right, you will end up with this table:
| 1 | 17 | 23 | 263 | 271 | 391 | 4,471 | 4,607 | 6,049 | 6,233 | 71,273 | 102,833 | 105,961 | 1,211,641 | 1,639,279 | 27,867,743 |
| -1 | -17 | -23 | -263 | -271 | -391 | -4,471 | -4,607 | -6,049 | -6,233 | -71,273 | -102,833 | -105,961 | -1,211,641 | -1,639,279 | -27,867,743 |
