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 26,571,557, 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 | 26,571,557 | |
| -1 | -26,571,557 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 26,571,557.
Example:
1 x 26,571,557 = 26,571,557
and
-1 x -26,571,557 = 26,571,557
Notice both answers equal 26,571,557
With that explanation out of the way, let's continue. Next, we take the number 26,571,557 and divide it by 2:
26,571,557 ÷ 2 = 13,285,778.5
If the quotient is a whole number, then 2 and 13,285,778.5 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 | 26,571,557 | |
| -1 | -26,571,557 |
Now, we try dividing 26,571,557 by 3:
26,571,557 ÷ 3 = 8,857,185.6667
If the quotient is a whole number, then 3 and 8,857,185.6667 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 | 26,571,557 | |
| -1 | -26,571,557 |
Let's try dividing by 4:
26,571,557 ÷ 4 = 6,642,889.25
If the quotient is a whole number, then 4 and 6,642,889.25 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 | 26,571,557 | |
| -1 | 26,571,557 |
If you did it right, you will end up with this table:
| 1 | 19 | 31 | 197 | 229 | 589 | 3,743 | 4,351 | 6,107 | 7,099 | 45,113 | 116,033 | 134,881 | 857,147 | 1,398,503 | 26,571,557 |
| -1 | -19 | -31 | -197 | -229 | -589 | -3,743 | -4,351 | -6,107 | -7,099 | -45,113 | -116,033 | -134,881 | -857,147 | -1,398,503 | -26,571,557 |
