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 26,422,231, 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 | 26,422,231 | |
| -1 | -26,422,231 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 26,422,231.
Example:
1 x 26,422,231 = 26,422,231
and
-1 x -26,422,231 = 26,422,231
Notice both answers equal 26,422,231
With that explanation out of the way, let's continue. Next, we take the number 26,422,231 and divide it by 2:
26,422,231 ÷ 2 = 13,211,115.5
If the quotient is a whole number, then 2 and 13,211,115.5 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 | 26,422,231 | |
| -1 | -26,422,231 |
Now, we try dividing 26,422,231 by 3:
26,422,231 ÷ 3 = 8,807,410.3333
If the quotient is a whole number, then 3 and 8,807,410.3333 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 | 26,422,231 | |
| -1 | -26,422,231 |
Let's try dividing by 4:
26,422,231 ÷ 4 = 6,605,557.75
If the quotient is a whole number, then 4 and 6,605,557.75 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 | 26,422,231 | |
| -1 | 26,422,231 |
If you did it right, you will end up with this table:
| 1 | 11 | 89 | 137 | 197 | 979 | 1,507 | 2,167 | 12,193 | 17,533 | 26,989 | 134,123 | 192,863 | 296,879 | 2,402,021 | 26,422,231 |
| -1 | -11 | -89 | -137 | -197 | -979 | -1,507 | -2,167 | -12,193 | -17,533 | -26,989 | -134,123 | -192,863 | -296,879 | -2,402,021 | -26,422,231 |
