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 26,261,545, 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 | 26,261,545 | |
| -1 | -26,261,545 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 26,261,545.
Example:
1 x 26,261,545 = 26,261,545
and
-1 x -26,261,545 = 26,261,545
Notice both answers equal 26,261,545
With that explanation out of the way, let's continue. Next, we take the number 26,261,545 and divide it by 2:
26,261,545 ÷ 2 = 13,130,772.5
If the quotient is a whole number, then 2 and 13,130,772.5 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 | 26,261,545 | |
| -1 | -26,261,545 |
Now, we try dividing 26,261,545 by 3:
26,261,545 ÷ 3 = 8,753,848.3333
If the quotient is a whole number, then 3 and 8,753,848.3333 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 | 26,261,545 | |
| -1 | -26,261,545 |
Let's try dividing by 4:
26,261,545 ÷ 4 = 6,565,386.25
If the quotient is a whole number, then 4 and 6,565,386.25 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 | 26,261,545 | |
| -1 | 26,261,545 |
If you did it right, you will end up with this table:
| 1 | 5 | 107 | 191 | 257 | 535 | 955 | 1,285 | 20,437 | 27,499 | 49,087 | 102,185 | 137,495 | 245,435 | 5,252,309 | 26,261,545 |
| -1 | -5 | -107 | -191 | -257 | -535 | -955 | -1,285 | -20,437 | -27,499 | -49,087 | -102,185 | -137,495 | -245,435 | -5,252,309 | -26,261,545 |
