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 26,845,271, 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 | 26,845,271 | |
| -1 | -26,845,271 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 26,845,271.
Example:
1 x 26,845,271 = 26,845,271
and
-1 x -26,845,271 = 26,845,271
Notice both answers equal 26,845,271
With that explanation out of the way, let's continue. Next, we take the number 26,845,271 and divide it by 2:
26,845,271 ÷ 2 = 13,422,635.5
If the quotient is a whole number, then 2 and 13,422,635.5 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 | 26,845,271 | |
| -1 | -26,845,271 |
Now, we try dividing 26,845,271 by 3:
26,845,271 ÷ 3 = 8,948,423.6667
If the quotient is a whole number, then 3 and 8,948,423.6667 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 | 26,845,271 | |
| -1 | -26,845,271 |
Let's try dividing by 4:
26,845,271 ÷ 4 = 6,711,317.75
If the quotient is a whole number, then 4 and 6,711,317.75 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 | 26,845,271 | |
| -1 | 26,845,271 |
If you did it right, you will end up with this table:
| 1 | 19 | 29 | 83 | 551 | 587 | 1,577 | 2,407 | 11,153 | 17,023 | 45,733 | 48,721 | 323,437 | 925,699 | 1,412,909 | 26,845,271 |
| -1 | -19 | -29 | -83 | -551 | -587 | -1,577 | -2,407 | -11,153 | -17,023 | -45,733 | -48,721 | -323,437 | -925,699 | -1,412,909 | -26,845,271 |
