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 27,618,409, 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 | 27,618,409 | |
| -1 | -27,618,409 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 27,618,409.
Example:
1 x 27,618,409 = 27,618,409
and
-1 x -27,618,409 = 27,618,409
Notice both answers equal 27,618,409
With that explanation out of the way, let's continue. Next, we take the number 27,618,409 and divide it by 2:
27,618,409 ÷ 2 = 13,809,204.5
If the quotient is a whole number, then 2 and 13,809,204.5 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 | 27,618,409 | |
| -1 | -27,618,409 |
Now, we try dividing 27,618,409 by 3:
27,618,409 ÷ 3 = 9,206,136.3333
If the quotient is a whole number, then 3 and 9,206,136.3333 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 | 27,618,409 | |
| -1 | -27,618,409 |
Let's try dividing by 4:
27,618,409 ÷ 4 = 6,904,602.25
If the quotient is a whole number, then 4 and 6,904,602.25 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 | 27,618,409 | |
| -1 | 27,618,409 |
If you did it right, you will end up with this table:
| 1 | 7 | 13 | 49 | 91 | 191 | 227 | 637 | 1,337 | 1,589 | 2,483 | 2,951 | 9,359 | 11,123 | 17,381 | 20,657 | 43,357 | 121,667 | 144,599 | 303,499 | 563,641 | 2,124,493 | 3,945,487 | 27,618,409 |
| -1 | -7 | -13 | -49 | -91 | -191 | -227 | -637 | -1,337 | -1,589 | -2,483 | -2,951 | -9,359 | -11,123 | -17,381 | -20,657 | -43,357 | -121,667 | -144,599 | -303,499 | -563,641 | -2,124,493 | -3,945,487 | -27,618,409 |
