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 27,633,617, 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 | 27,633,617 | |
| -1 | -27,633,617 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 27,633,617.
Example:
1 x 27,633,617 = 27,633,617
and
-1 x -27,633,617 = 27,633,617
Notice both answers equal 27,633,617
With that explanation out of the way, let's continue. Next, we take the number 27,633,617 and divide it by 2:
27,633,617 ÷ 2 = 13,816,808.5
If the quotient is a whole number, then 2 and 13,816,808.5 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 | 27,633,617 | |
| -1 | -27,633,617 |
Now, we try dividing 27,633,617 by 3:
27,633,617 ÷ 3 = 9,211,205.6667
If the quotient is a whole number, then 3 and 9,211,205.6667 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 | 27,633,617 | |
| -1 | -27,633,617 |
Let's try dividing by 4:
27,633,617 ÷ 4 = 6,908,404.25
If the quotient is a whole number, then 4 and 6,908,404.25 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 | 27,633,617 | |
| -1 | 27,633,617 |
If you did it right, you will end up with this table:
| 1 | 11 | 31 | 53 | 121 | 139 | 341 | 583 | 1,529 | 1,643 | 3,751 | 4,309 | 6,413 | 7,367 | 16,819 | 18,073 | 47,399 | 81,037 | 198,803 | 228,377 | 521,389 | 891,407 | 2,512,147 | 27,633,617 |
| -1 | -11 | -31 | -53 | -121 | -139 | -341 | -583 | -1,529 | -1,643 | -3,751 | -4,309 | -6,413 | -7,367 | -16,819 | -18,073 | -47,399 | -81,037 | -198,803 | -228,377 | -521,389 | -891,407 | -2,512,147 | -27,633,617 |
