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 26,271,623, 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 | 26,271,623 | |
| -1 | -26,271,623 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 26,271,623.
Example:
1 x 26,271,623 = 26,271,623
and
-1 x -26,271,623 = 26,271,623
Notice both answers equal 26,271,623
With that explanation out of the way, let's continue. Next, we take the number 26,271,623 and divide it by 2:
26,271,623 ÷ 2 = 13,135,811.5
If the quotient is a whole number, then 2 and 13,135,811.5 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 | 26,271,623 | |
| -1 | -26,271,623 |
Now, we try dividing 26,271,623 by 3:
26,271,623 ÷ 3 = 8,757,207.6667
If the quotient is a whole number, then 3 and 8,757,207.6667 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 | 26,271,623 | |
| -1 | -26,271,623 |
Let's try dividing by 4:
26,271,623 ÷ 4 = 6,567,905.75
If the quotient is a whole number, then 4 and 6,567,905.75 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 | 26,271,623 | |
| -1 | 26,271,623 |
If you did it right, you will end up with this table:
| 1 | 7 | 19 | 53 | 133 | 371 | 1,007 | 3,727 | 7,049 | 26,089 | 70,813 | 197,531 | 495,691 | 1,382,717 | 3,753,089 | 26,271,623 |
| -1 | -7 | -19 | -53 | -133 | -371 | -1,007 | -3,727 | -7,049 | -26,089 | -70,813 | -197,531 | -495,691 | -1,382,717 | -3,753,089 | -26,271,623 |
