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 26,423,929, 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 | 26,423,929 | |
| -1 | -26,423,929 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 26,423,929.
Example:
1 x 26,423,929 = 26,423,929
and
-1 x -26,423,929 = 26,423,929
Notice both answers equal 26,423,929
With that explanation out of the way, let's continue. Next, we take the number 26,423,929 and divide it by 2:
26,423,929 ÷ 2 = 13,211,964.5
If the quotient is a whole number, then 2 and 13,211,964.5 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 | 26,423,929 | |
| -1 | -26,423,929 |
Now, we try dividing 26,423,929 by 3:
26,423,929 ÷ 3 = 8,807,976.3333
If the quotient is a whole number, then 3 and 8,807,976.3333 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 | 26,423,929 | |
| -1 | -26,423,929 |
Let's try dividing by 4:
26,423,929 ÷ 4 = 6,605,982.25
If the quotient is a whole number, then 4 and 6,605,982.25 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 | 26,423,929 | |
| -1 | 26,423,929 |
If you did it right, you will end up with this table:
| 1 | 7 | 67 | 103 | 469 | 547 | 721 | 3,829 | 6,901 | 36,649 | 48,307 | 56,341 | 256,543 | 394,387 | 3,774,847 | 26,423,929 |
| -1 | -7 | -67 | -103 | -469 | -547 | -721 | -3,829 | -6,901 | -36,649 | -48,307 | -56,341 | -256,543 | -394,387 | -3,774,847 | -26,423,929 |
