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 26,362,537, 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 | 26,362,537 | |
| -1 | -26,362,537 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 26,362,537.
Example:
1 x 26,362,537 = 26,362,537
and
-1 x -26,362,537 = 26,362,537
Notice both answers equal 26,362,537
With that explanation out of the way, let's continue. Next, we take the number 26,362,537 and divide it by 2:
26,362,537 ÷ 2 = 13,181,268.5
If the quotient is a whole number, then 2 and 13,181,268.5 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 | 26,362,537 | |
| -1 | -26,362,537 |
Now, we try dividing 26,362,537 by 3:
26,362,537 ÷ 3 = 8,787,512.3333
If the quotient is a whole number, then 3 and 8,787,512.3333 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 | 26,362,537 | |
| -1 | -26,362,537 |
Let's try dividing by 4:
26,362,537 ÷ 4 = 6,590,634.25
If the quotient is a whole number, then 4 and 6,590,634.25 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 | 26,362,537 | |
| -1 | 26,362,537 |
If you did it right, you will end up with this table:
| 1 | 29 | 37 | 79 | 311 | 1,073 | 2,291 | 2,923 | 9,019 | 11,507 | 24,569 | 84,767 | 333,703 | 712,501 | 909,053 | 26,362,537 |
| -1 | -29 | -37 | -79 | -311 | -1,073 | -2,291 | -2,923 | -9,019 | -11,507 | -24,569 | -84,767 | -333,703 | -712,501 | -909,053 | -26,362,537 |
