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 27,762,863, 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 | 27,762,863 | |
| -1 | -27,762,863 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 27,762,863.
Example:
1 x 27,762,863 = 27,762,863
and
-1 x -27,762,863 = 27,762,863
Notice both answers equal 27,762,863
With that explanation out of the way, let's continue. Next, we take the number 27,762,863 and divide it by 2:
27,762,863 ÷ 2 = 13,881,431.5
If the quotient is a whole number, then 2 and 13,881,431.5 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 | 27,762,863 | |
| -1 | -27,762,863 |
Now, we try dividing 27,762,863 by 3:
27,762,863 ÷ 3 = 9,254,287.6667
If the quotient is a whole number, then 3 and 9,254,287.6667 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 | 27,762,863 | |
| -1 | -27,762,863 |
Let's try dividing by 4:
27,762,863 ÷ 4 = 6,940,715.75
If the quotient is a whole number, then 4 and 6,940,715.75 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 | 27,762,863 | |
| -1 | 27,762,863 |
If you did it right, you will end up with this table:
| 1 | 23 | 41 | 59 | 499 | 943 | 1,357 | 2,419 | 11,477 | 20,459 | 29,441 | 55,637 | 470,557 | 677,143 | 1,207,081 | 27,762,863 |
| -1 | -23 | -41 | -59 | -499 | -943 | -1,357 | -2,419 | -11,477 | -20,459 | -29,441 | -55,637 | -470,557 | -677,143 | -1,207,081 | -27,762,863 |
