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 26,938,355, 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 | 26,938,355 | |
| -1 | -26,938,355 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 26,938,355.
Example:
1 x 26,938,355 = 26,938,355
and
-1 x -26,938,355 = 26,938,355
Notice both answers equal 26,938,355
With that explanation out of the way, let's continue. Next, we take the number 26,938,355 and divide it by 2:
26,938,355 ÷ 2 = 13,469,177.5
If the quotient is a whole number, then 2 and 13,469,177.5 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 | 26,938,355 | |
| -1 | -26,938,355 |
Now, we try dividing 26,938,355 by 3:
26,938,355 ÷ 3 = 8,979,451.6667
If the quotient is a whole number, then 3 and 8,979,451.6667 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 | 26,938,355 | |
| -1 | -26,938,355 |
Let's try dividing by 4:
26,938,355 ÷ 4 = 6,734,588.75
If the quotient is a whole number, then 4 and 6,734,588.75 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 | 26,938,355 | |
| -1 | 26,938,355 |
If you did it right, you will end up with this table:
| 1 | 5 | 67 | 97 | 335 | 485 | 829 | 4,145 | 6,499 | 32,495 | 55,543 | 80,413 | 277,715 | 402,065 | 5,387,671 | 26,938,355 |
| -1 | -5 | -67 | -97 | -335 | -485 | -829 | -4,145 | -6,499 | -32,495 | -55,543 | -80,413 | -277,715 | -402,065 | -5,387,671 | -26,938,355 |
