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 26,576,231, 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 | 26,576,231 | |
| -1 | -26,576,231 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 26,576,231.
Example:
1 x 26,576,231 = 26,576,231
and
-1 x -26,576,231 = 26,576,231
Notice both answers equal 26,576,231
With that explanation out of the way, let's continue. Next, we take the number 26,576,231 and divide it by 2:
26,576,231 ÷ 2 = 13,288,115.5
If the quotient is a whole number, then 2 and 13,288,115.5 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 | 26,576,231 | |
| -1 | -26,576,231 |
Now, we try dividing 26,576,231 by 3:
26,576,231 ÷ 3 = 8,858,743.6667
If the quotient is a whole number, then 3 and 8,858,743.6667 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 | 26,576,231 | |
| -1 | -26,576,231 |
Let's try dividing by 4:
26,576,231 ÷ 4 = 6,644,057.75
If the quotient is a whole number, then 4 and 6,644,057.75 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 | 26,576,231 | |
| -1 | 26,576,231 |
If you did it right, you will end up with this table:
| 1 | 11 | 19 | 101 | 209 | 1,111 | 1,259 | 1,919 | 13,849 | 21,109 | 23,921 | 127,159 | 263,131 | 1,398,749 | 2,416,021 | 26,576,231 |
| -1 | -11 | -19 | -101 | -209 | -1,111 | -1,259 | -1,919 | -13,849 | -21,109 | -23,921 | -127,159 | -263,131 | -1,398,749 | -2,416,021 | -26,576,231 |
