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 26,331,335, 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 | 26,331,335 | |
| -1 | -26,331,335 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 26,331,335.
Example:
1 x 26,331,335 = 26,331,335
and
-1 x -26,331,335 = 26,331,335
Notice both answers equal 26,331,335
With that explanation out of the way, let's continue. Next, we take the number 26,331,335 and divide it by 2:
26,331,335 ÷ 2 = 13,165,667.5
If the quotient is a whole number, then 2 and 13,165,667.5 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 | 26,331,335 | |
| -1 | -26,331,335 |
Now, we try dividing 26,331,335 by 3:
26,331,335 ÷ 3 = 8,777,111.6667
If the quotient is a whole number, then 3 and 8,777,111.6667 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 | 26,331,335 | |
| -1 | -26,331,335 |
Let's try dividing by 4:
26,331,335 ÷ 4 = 6,582,833.75
If the quotient is a whole number, then 4 and 6,582,833.75 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 | 26,331,335 | |
| -1 | 26,331,335 |
If you did it right, you will end up with this table:
| 1 | 5 | 67 | 83 | 335 | 415 | 947 | 4,735 | 5,561 | 27,805 | 63,449 | 78,601 | 317,245 | 393,005 | 5,266,267 | 26,331,335 |
| -1 | -5 | -67 | -83 | -335 | -415 | -947 | -4,735 | -5,561 | -27,805 | -63,449 | -78,601 | -317,245 | -393,005 | -5,266,267 | -26,331,335 |
