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 26,566,579, 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 | 26,566,579 | |
| -1 | -26,566,579 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 26,566,579.
Example:
1 x 26,566,579 = 26,566,579
and
-1 x -26,566,579 = 26,566,579
Notice both answers equal 26,566,579
With that explanation out of the way, let's continue. Next, we take the number 26,566,579 and divide it by 2:
26,566,579 ÷ 2 = 13,283,289.5
If the quotient is a whole number, then 2 and 13,283,289.5 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 | 26,566,579 | |
| -1 | -26,566,579 |
Now, we try dividing 26,566,579 by 3:
26,566,579 ÷ 3 = 8,855,526.3333
If the quotient is a whole number, then 3 and 8,855,526.3333 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 | 26,566,579 | |
| -1 | -26,566,579 |
Let's try dividing by 4:
26,566,579 ÷ 4 = 6,641,644.75
If the quotient is a whole number, then 4 and 6,641,644.75 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 | 26,566,579 | |
| -1 | 26,566,579 |
If you did it right, you will end up with this table:
| 1 | 13 | 19 | 59 | 247 | 767 | 1,121 | 1,823 | 14,573 | 23,699 | 34,637 | 107,557 | 450,281 | 1,398,241 | 2,043,583 | 26,566,579 |
| -1 | -13 | -19 | -59 | -247 | -767 | -1,121 | -1,823 | -14,573 | -23,699 | -34,637 | -107,557 | -450,281 | -1,398,241 | -2,043,583 | -26,566,579 |
