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 25,926,899, 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 | 25,926,899 | |
| -1 | -25,926,899 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 25,926,899.
Example:
1 x 25,926,899 = 25,926,899
and
-1 x -25,926,899 = 25,926,899
Notice both answers equal 25,926,899
With that explanation out of the way, let's continue. Next, we take the number 25,926,899 and divide it by 2:
25,926,899 ÷ 2 = 12,963,449.5
If the quotient is a whole number, then 2 and 12,963,449.5 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 | 25,926,899 | |
| -1 | -25,926,899 |
Now, we try dividing 25,926,899 by 3:
25,926,899 ÷ 3 = 8,642,299.6667
If the quotient is a whole number, then 3 and 8,642,299.6667 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 | 25,926,899 | |
| -1 | -25,926,899 |
Let's try dividing by 4:
25,926,899 ÷ 4 = 6,481,724.75
If the quotient is a whole number, then 4 and 6,481,724.75 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 | 25,926,899 | |
| -1 | 25,926,899 |
If you did it right, you will end up with this table:
| 1 | 29 | 37 | 73 | 331 | 1,073 | 2,117 | 2,701 | 9,599 | 12,247 | 24,163 | 78,329 | 355,163 | 700,727 | 894,031 | 25,926,899 |
| -1 | -29 | -37 | -73 | -331 | -1,073 | -2,117 | -2,701 | -9,599 | -12,247 | -24,163 | -78,329 | -355,163 | -700,727 | -894,031 | -25,926,899 |
