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 26,543,135, 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 | 26,543,135 | |
| -1 | -26,543,135 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 26,543,135.
Example:
1 x 26,543,135 = 26,543,135
and
-1 x -26,543,135 = 26,543,135
Notice both answers equal 26,543,135
With that explanation out of the way, let's continue. Next, we take the number 26,543,135 and divide it by 2:
26,543,135 ÷ 2 = 13,271,567.5
If the quotient is a whole number, then 2 and 13,271,567.5 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 | 26,543,135 | |
| -1 | -26,543,135 |
Now, we try dividing 26,543,135 by 3:
26,543,135 ÷ 3 = 8,847,711.6667
If the quotient is a whole number, then 3 and 8,847,711.6667 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 | 26,543,135 | |
| -1 | -26,543,135 |
Let's try dividing by 4:
26,543,135 ÷ 4 = 6,635,783.75
If the quotient is a whole number, then 4 and 6,635,783.75 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 | 26,543,135 | |
| -1 | 26,543,135 |
If you did it right, you will end up with this table:
| 1 | 5 | 109 | 113 | 431 | 545 | 565 | 2,155 | 12,317 | 46,979 | 48,703 | 61,585 | 234,895 | 243,515 | 5,308,627 | 26,543,135 |
| -1 | -5 | -109 | -113 | -431 | -545 | -565 | -2,155 | -12,317 | -46,979 | -48,703 | -61,585 | -234,895 | -243,515 | -5,308,627 | -26,543,135 |
