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 27,634,661, 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 | 27,634,661 | |
| -1 | -27,634,661 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 27,634,661.
Example:
1 x 27,634,661 = 27,634,661
and
-1 x -27,634,661 = 27,634,661
Notice both answers equal 27,634,661
With that explanation out of the way, let's continue. Next, we take the number 27,634,661 and divide it by 2:
27,634,661 ÷ 2 = 13,817,330.5
If the quotient is a whole number, then 2 and 13,817,330.5 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 | 27,634,661 | |
| -1 | -27,634,661 |
Now, we try dividing 27,634,661 by 3:
27,634,661 ÷ 3 = 9,211,553.6667
If the quotient is a whole number, then 3 and 9,211,553.6667 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 | 27,634,661 | |
| -1 | -27,634,661 |
Let's try dividing by 4:
27,634,661 ÷ 4 = 6,908,665.25
If the quotient is a whole number, then 4 and 6,908,665.25 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 | 27,634,661 | |
| -1 | 27,634,661 |
If you did it right, you will end up with this table:
| 1 | 23 | 73 | 109 | 151 | 1,679 | 2,507 | 3,473 | 7,957 | 11,023 | 16,459 | 183,011 | 253,529 | 378,557 | 1,201,507 | 27,634,661 |
| -1 | -23 | -73 | -109 | -151 | -1,679 | -2,507 | -3,473 | -7,957 | -11,023 | -16,459 | -183,011 | -253,529 | -378,557 | -1,201,507 | -27,634,661 |
