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 9,726,925, 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 | 9,726,925 | |
| -1 | -9,726,925 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 9,726,925.
Example:
1 x 9,726,925 = 9,726,925
and
-1 x -9,726,925 = 9,726,925
Notice both answers equal 9,726,925
With that explanation out of the way, let's continue. Next, we take the number 9,726,925 and divide it by 2:
9,726,925 ÷ 2 = 4,863,462.5
If the quotient is a whole number, then 2 and 4,863,462.5 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 | 9,726,925 | |
| -1 | -9,726,925 |
Now, we try dividing 9,726,925 by 3:
9,726,925 ÷ 3 = 3,242,308.3333
If the quotient is a whole number, then 3 and 3,242,308.3333 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 | 9,726,925 | |
| -1 | -9,726,925 |
Let's try dividing by 4:
9,726,925 ÷ 4 = 2,431,731.25
If the quotient is a whole number, then 4 and 2,431,731.25 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 | 9,726,925 | |
| -1 | 9,726,925 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 25 | 65 | 173 | 325 | 865 | 2,249 | 4,325 | 11,245 | 29,929 | 56,225 | 149,645 | 389,077 | 748,225 | 1,945,385 | 9,726,925 |
| -1 | -5 | -13 | -25 | -65 | -173 | -325 | -865 | -2,249 | -4,325 | -11,245 | -29,929 | -56,225 | -149,645 | -389,077 | -748,225 | -1,945,385 | -9,726,925 |
