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 26,326,075, 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 | 26,326,075 | |
| -1 | -26,326,075 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 26,326,075.
Example:
1 x 26,326,075 = 26,326,075
and
-1 x -26,326,075 = 26,326,075
Notice both answers equal 26,326,075
With that explanation out of the way, let's continue. Next, we take the number 26,326,075 and divide it by 2:
26,326,075 ÷ 2 = 13,163,037.5
If the quotient is a whole number, then 2 and 13,163,037.5 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 | 26,326,075 | |
| -1 | -26,326,075 |
Now, we try dividing 26,326,075 by 3:
26,326,075 ÷ 3 = 8,775,358.3333
If the quotient is a whole number, then 3 and 8,775,358.3333 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 | 26,326,075 | |
| -1 | -26,326,075 |
Let's try dividing by 4:
26,326,075 ÷ 4 = 6,581,518.75
If the quotient is a whole number, then 4 and 6,581,518.75 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 | 26,326,075 | |
| -1 | 26,326,075 |
If you did it right, you will end up with this table:
| 1 | 5 | 25 | 61 | 283 | 305 | 1,415 | 1,525 | 3,721 | 7,075 | 17,263 | 18,605 | 86,315 | 93,025 | 431,575 | 1,053,043 | 5,265,215 | 26,326,075 |
| -1 | -5 | -25 | -61 | -283 | -305 | -1,415 | -1,525 | -3,721 | -7,075 | -17,263 | -18,605 | -86,315 | -93,025 | -431,575 | -1,053,043 | -5,265,215 | -26,326,075 |
