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 26,423,705, 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 | 26,423,705 | |
| -1 | -26,423,705 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 26,423,705.
Example:
1 x 26,423,705 = 26,423,705
and
-1 x -26,423,705 = 26,423,705
Notice both answers equal 26,423,705
With that explanation out of the way, let's continue. Next, we take the number 26,423,705 and divide it by 2:
26,423,705 ÷ 2 = 13,211,852.5
If the quotient is a whole number, then 2 and 13,211,852.5 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 | 26,423,705 | |
| -1 | -26,423,705 |
Now, we try dividing 26,423,705 by 3:
26,423,705 ÷ 3 = 8,807,901.6667
If the quotient is a whole number, then 3 and 8,807,901.6667 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 | 26,423,705 | |
| -1 | -26,423,705 |
Let's try dividing by 4:
26,423,705 ÷ 4 = 6,605,926.25
If the quotient is a whole number, then 4 and 6,605,926.25 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 | 26,423,705 | |
| -1 | 26,423,705 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 11 | 35 | 55 | 77 | 385 | 68,633 | 343,165 | 480,431 | 754,963 | 2,402,155 | 3,774,815 | 5,284,741 | 26,423,705 |
| -1 | -5 | -7 | -11 | -35 | -55 | -77 | -385 | -68,633 | -343,165 | -480,431 | -754,963 | -2,402,155 | -3,774,815 | -5,284,741 | -26,423,705 |
